Why did the ancient city gates open inward?

The ancients had many brilliant achievements in architecture, and of course there were many rules that were difficult for us modern people to understand, such as in times of war, we can often see that the gates of each city are open inwardAnd in the minds of many of us, this is tantamount to putting the enemy in. But in fact, in that era of cold weapons, opening the city gate inward can not only effectively prevent the enemy from attacking the city gate, but also has many other functions and intentions. <>

1. The door facing out is the real danger Imagine that if the gate of the ancient city was facing outward, wouldn't it be convenient for the outside to open the city gate or knock on the city gate, and according to the physical force, it is very difficult for the people inside to protect the city gate. Therefore, once the gate is opened outward, then, once the war reaches the point of dire straits, the capture of the city gate becomes the enemy's most willing and most victorious move, and it is difficult for the officers and soldiers defending the city to hold even the last line of defense. <>

Second, there is a suspension bridge outside the city gate In the design of the ancient city gate, there are not only the two gates of the city gate, but also a suspension bridge auxiliary, so that when the city gate is opened to the inside, the role of the suspension bridge will become very large. Allies who want to enter the city gate outside can enter the city gate as long as they step on the drawbridge. If the city gate is designed outward, then the suspension bridge will be pressed against the city gate, which is very unreasonable.

So the gates were opened inward so that the drawbridge could be used to welcome aid. <>

3. Open inward to maintain the ancient city gate is to open inward for so long to hit the city wall, that is, the inner city wall, so that it is easy to repair the damage. If it is opened outward, then it will not be able to touch the wall from the outside, and the opening angle will be opened beyond the limit, which will also cause excessive damage. Therefore, keeping the city gate inward is conducive to long-term maintenance.

Finally, the design of the city gate is also to ensure the peace of one side, to make a city relatively strong, so it will not open to the outside, which is the fundamental reason why the city gate must be open inward.

Because the doors in ancient times were all wooden doors, the enemy just set fire to it, there is no reason why it is easier for the enemy to open it inward than outward, the real reason is that opening inward can protect the soldiers who close the door from going out.

In addition, after closing the city gate, you can block sandbags to protect against enemies, reducing the chance of the gate being pushed open, and giving you more time to prepare for the enemy.

The city gate is open inward, the defense ability is stronger, the material of the city gate is made of wood, open inside, not easy to be wet by the rain, the city gate is open inward has the meaning of "tolerance".

When we watch costume movies and television dramas, careful friends may find that in ancient times, whether it was a city gate, a temple gate or a house door where ordinary people lived, it was not the same as the door of our modern people. In ancient times, the direction of the door was opposite to that of the door today. We now have doors open to the outside.

In ancient times, the doors were opened inward. Why is there such a contrast? What is the purpose of opening the door inside?

Here we take the ancient city gate as an example to analyze the reason why the ancient city gate opened inward.

First of all, the installation structure of ancient doors, and our modern doors, is different. Ancient doors were not mounted on door frames. Due to the heavy and tall city gate, it needed to be installed on the inside of the door frame and on the pivot of the inner wall of the house, and the two gates had to rotate around the hub.

And the hub must be fixed to the wall, because there is a high threshold in front of the two doors, so the ancient city gate can only rotate inward, and the door can only be opened inward.

Secondly, in order to defend the enemy from breaking the city. As we all know, the ancient city gate was an important line of defense to protect the safety of the country and the people. Therefore, the gates of the city were opened inward for safety.

In battle, the enemy usually pushes the door from the outside to the inside, and if the gate is open to the outside, it will be more dangerous for the soldiers to close the door once the enemy is under the city. When the people inside the city close the door, the enemy outside the city will open the door by chance, and then such a gate will lose its defensive function, and the gate will be as if it were a void.

Again, outside the ancient city gates, a moat would be dug and a huge suspension bridge would be installed on top of the moat. If the gates were to be opened, the huge drawbridge would not be able to rise because of the gates. And the suspension bridge and the ground are not completely level, uneven.

Therefore, the gates could only be opened inward.

The main thing is to open inward to better close the city gate when the enemy attacks in, or it is estimated that it will become a sieve when the city gate is not closed.

In ancient times, people were more intelligent and hospitable, so they set the door to open inward, and it was windy and rainy all year round, and if it was opened outward, it would slowly rot.

It is beneficial to protect the city gatesThe ancient city gate can certainly play a role in preventing enemy troops from rushing into the city, but that is not its main role. In ancient wars, when a siege war occurred, outside the city gate, where the city defense was the weakest, it was often necessary to garrison heavy troops and fight a decisive battle outside the city.

The majestic appearance of the city gate and the castle tower shows the majesty of the city and the demeanor of the nation. In ancient times, there was a moat outside the city gate, and there was a drawbridge in front of it, and when fighting, it was generally the enemy who attacked the city from outside the cityIf the city gate is opened, then when the soldiers in the city close, they will inevitably pull the city gate inward, and the defending soldiers will not be covered, and they will become a living target for the enemy

This was built according to the realities of the time, on the one hand, for convenience, and on the other hand, from the war situation.

In ancient times, etiquette was highly valued, and the opening of the door inward meant that the country was very tolerant.

I think it's probably because it's beautiful to open inward, and it's sturdy when it's closed, after all, I often fight.

Opening the gate inward can be used to secure the gate by stacking boulders and sandbags on the inside of the gate when the enemy is coming to close the gate, but opening it outward will not be able to strengthen the gate with piles.

In many historical plays, we can see many scenes of ancient wars. In ancient feudal society, wars were frequent, sometimes warlords divided and sometimes fought between countries.

More often than not, there will be a change of regime or even a dynasty. Magnificent wars and desolate battlefields have always been the hallmarks of ancient warfare. And in many cases, ancient warfare can also reflect the most simple wisdom of the ancients.

Imagine if the city gates were to be opened outward, and in the event of an invasion by a foreign enemy, the soldiers would have to go out of the city first, completely exposed to the noses of the foreign enemy, before they could push the heavy city gates. Maybe before the door was closed, he would die under the arrows. When a soldier dies and the city gate is not closed, isn't it equivalent to giving the city to the other party?

Secondly, because the ancient city gate was not mounted on the door frame with hinges, but inserted on the "hub", and the gate rotated around the axis, the hub was set on the inside, and the gate naturally opened inward.

However, if the hub is set on the outside, the gate will be as if it were a non-existent gate, and if someone breaks it, the gate will fall.

In addition, if someone placed a barrier outside the city gate, the soldiers could not push the gate open, and the people in the city were imprisoned like turtles in an urn. The advantage of the city gate inward is that you don't have to worry about being hindered when you open and close, and even the city gate can be used as a shield for the soldiers.

Finally, in order to maintain the city gate, most of the ancient city gates were made of wood, although they were inlaid with copper nails to strengthen the defense ability, but they were still wooden doors after all, and they could not afford to be exposed to the sun and rain for a long time, so when the city gate was opened inside, the wooden gate would be placed in the door hole of the city wall to "hide from the rain and the sun", and this could also reduce the obstacles to people's passage.

In addition, most castles will have moats outside the castle, so there will inevitably be drawbridges to facilitate traffic, and if the gates are opened outward, there is a high probability that the two will get stuck in each other, causing a dilemma that cannot be opened, so most of the gates will be opened inward.

Our country has been a big country of etiquette since ancient times, and the city gate as the face of a country is indispensable for etiquette, and the city gate that is open inward means that our country is tolerant and welcomes all those who come to visit, and what if the city gate is open outward? The guests have already walked to the front of the door, and when the door is opened, the guests can not be allowed to give way back, which is inconsistent with the "etiquette", so the city gate opened inward can reflect that our country is a real state of etiquette.

Protect the city gates. In ancient times, most of the city gates were built of wood, if the city gate was open to the outside for a long time, it would inevitably be eroded by rainwater, and the wood would swell and even perishable when exposed to water.

Prevents the gates from being knocked open from the outside. When the enemy army hits the city gate, the defenders can resist the city gate. To prevent outsiders from entering, once the city gate is closed, no one can enter from the outside.

It is to resist the thieves, it is easier to control yourself when you open inward, and you can control the power inside, and you can open as big as you want.

Many people may feel that opening the city gate to the inside is not to make the besiegers better to push the doorAfter breaking the door, if you open it out, it won't be a push door but a sliding door, isn't it more difficult to pull the door than to push the door, so for defensive reasons, why not just set the door to open outward? It would be a mistake to think so!

Because the ancient city gates were all wooden gates, and a fire burned themIt doesn't matter where you go, so the ancients didn't design it from an offensive and defensive point of view. The reason why the gate is open to the inside is that when the enemy invades, the soldiers guarding the gate in the city can quickly close the gate from the inside without exposing it to the enemy, and then use stakes, stones, sandbags and other items behind the gate, so that it will not be so easy for the enemy to break through the gate.

Think about it, if the gates were open outward, the soldiers would have to go out of the gates and be completely exposed to enemy fire before they could close the gates. It's good to be able to close the gatesIf the gate is closed and he dies under the enemy's arrows, then the soldiers who closed the gate are killed, but the gate is not closed, so that it is not more convenient for the enemy to enter the city? Why did the ancient city gate open in?

After reading it, I realized that the ancients were so smart!

Moreover, because the ancient city gate is a wooden structure, the wooden gate will swell when it is dampRotten, the city gate is designed to be opened inside, which can protect the city gate from excessive wind, sun and rain, play a role in maintenance, and prolong the service life of the city gate. Wouldn't it be a great loss if the city gates were damaged by rain during the war? Therefore, the ancients were still very wise, and they considered the problem much more comprehensively than many modern people, which is really admirable!

In ancient times, the city gates were opened inward, why is this? You won't necessarily believe it.

Friends who love to watch historical dramas should know that in times of war, there is often such a scene - a large group of people holding a big thick pillar and hitting the city gate. It can be seen from this that the ancient city gates were open inward, so why is that?

I think the main reason is technical issues. We must know that in ancient times, there was no such thing as a door frame, so the doors were directly inserted into the "hub" inside the city wall, and the two door panels were directly rotated around the pivot to open. The hub is fixed to the wall, so the door can only be opened inward.

And friends who have visited ancient buildings must know that all doors in ancient times had thresholds. The threshold stood outside the door, originally to keep out the rain; Later, it was gradually given other meanings, such as being able to resist disasters and evils. As a result, the threshold was piled higher and higher, and the door could not be opened outward.

Another important point is to protect the gate, the ancient city gate was made of wood, even if it is heavy, it cannot withstand the erosion of wind and rain. Therefore, opening the door inward protects the city gate to a certain extent and increases its service life, which is the wisdom of the ancient people of our country.

The opening of the city gate to the interior is actually of strategic significance. In wartime, if the city gates are opened outward, then it is tantamount to giving the initiative to open the doors to the enemy. As long as the enemy piles some stones outside the gate, it will be difficult for the defenders to open the door from the inside, and being trapped in the city is tantamount to waiting for death.

In many places in Tohoku, the door is still open inward, and the principle is the same, the Tohoku snows continuously, and if the door is blocked by snow, then it is difficult to open the outward door.

And one more thing: this will prevent thieves! If the door is opened outward, it is easy for the thief to hide behind the door after opening the door, and people will inevitably go out to look, so that they are more vulnerable to the thief's attack.

The door that opens inward greatly reduces the possibility of thieves being so **, and increases security to a certain extent. The same is true of the city gates, and the larger the gates, the more dangers they hide.

The opening of the city gate to the inside actually reflects the excellent tradition of our country since ancient times - politeness. In ancient times, the city gate was the face of a city. If guests come downstairs, we must of course welcome them with open arms, and the open city gate represents our enthusiasm and humility.

Our motherland is a ceremonial country with a history of 5,000 years, and it is natural that even the city gate and other small things are covered.
