The east, west and north sides of the ancient city are precipitous cliffs, next to the lake, with natural danger as a barrier. The ancient city wall was built on the hillside, except that the south wall has an urn gate leading down the mountain. There are 15 castellations in the ancient city. The city is high in the north and low in the east, and the terrain is relatively flat. The ancient city wall was built on the mountain. The circumference of the city is about 3 kilometers. In the middle of the city, there is a partition wall that runs from east to west. There are dozens of castellations (horse faces) in the city. Only the south wall has an urn that can pass down the mountain.
It is said that it is OK, some people say only see the ruins, not the scenery, some say not good, or go to a while, some time.
It's the ancient city walls. Visit here to learn a bit of history, not very impressive, I don't think you need to go here specially to see that we come with the travel agency.
Just a small site, I feel more comfortable for older people to see and do, but also for those who like archaeology!
Some ancient walls, not strong, personal feel not to go here to see, personal opinions only for reference.
