Basic introduction of Luo Yan ancient city site

The site of the ancient city of Luo Yan belongs to the archaeological site of Beijing, a famous tourist resort.

The ancient city of Luo Yan is located in Luo Yan Village, Miyun County. Backed by Yunfeng Mountain, the east and west are hilly areas, and the south of the city is low-lying open space (now Miyun Reservoir). The city was originally built in the early years of Sui Dynasty. The ancient city is rectangular, with a concave southwest corner, slightly longer north and south, and shorter east and west. The circumference of the city is more than 2,840 meters, with an area of about 24 100 square meter. The wall is coarse sand and yellow cinnamon soil, and no rammed nest is found. At present, most of the north wall remains, with a residual height of more than 2 meters, and there seems to be architectural traces of the north gate in the middle. There are several sections on the east and west walls, some of which are about 3 meters high and some are less than 2 meters high, and the south wall is seriously damaged. But the ruins tour and the ancient city tour do bring people a lot of reverie and yearning for the past, hoping to feel the prosperity and prosperity of the past, which is a good adjustment and supplement to modern life and a good place to go.
