Jieshigong site is the largest of the six sites. It is the residence of the eastern boundary stone of Qin Shihuang and the main building of the whole site group. Its overall layout is rectangular, 500 meters long from north to south and 300 meters wide from east to west, covering an area of 6.5438+0.5 million square meters. There is a rammed earth wall around it, with a base width of 2.8 meters and steep inner and outer walls. The temple was built on the high rammed earth platform of the stone tablet. The three-dimensional building of the site is close to the coastline. The rammed earth platform left is 8m high and the foundation is 40m long. Half of it sank underground. This is a magnificent multi-storey building with a high platform. There are turrets on the two wings of the three-dimensional building, and there are many buildings behind it. Apart from Xianyang in Qin Dou and Chang 'an, the capital of Han Dynasty, it is rare to see such a large and orderly palace complex. The simple tile for building unearthed here has a large semicircle on the head and high embossed lines on the front, with a diameter of 54 cm, a tile height of 37 cm and a total length of 68 cm. It can be called "tile king" and is a special material for royal architecture in Qin Dynasty. Standardization of patterns is rare in China. Two thousand years ago, the rooms, drainage system and food storage pits in the palace were clearly visible. The southern end of the central axis of Jieshi Palace is opposite to Jiangnu Stone, the minister stone in the sea, which is more than 400 meters apart. Jiangnvshi was the Jieshi (Gate) in Qin and Han Dynasties. Jieshi Palace takes advantage of the coastal natural landscape and faces the endless Bohai Sea, where there are towering Jieshi. Behind the towering Yanshan Mountains, there is a Great Wall on the mountain. With the palace in the wall as the main building, Zhimiao Bay as the left-wing que building, Heishantou as the right-wing que building, surrounded by Wazidi, Zhou Jia, Jinsitun and many other ancillary buildings, it faces Jieshi (Gate) in the sea, forming a complete and spectacular building complex. It can be listed as the three major projects of the Qin Dynasty along with the First Imperial Tomb and Epang Palace. In the sea opposite Jieshi Palace, there are three grotesque rocks called Jieshi, which is also the tomb of Meng Jiangnv in historical legend. Jieshi stands by the sea and has a unique style. Seen from different angles, this stone has different effects. Looking at this stone on the black hill, it seems like a brown rooster standing on the sea, holding its neck up and crowing; Looking at this stone in front of the wall is like a young woman looking at the sea with a pair of children.

According to legend, Cao Cao, Emperor Wudi of Wei Dynasty, set three counties of Wu, western Liaoning and eastern Liaoning in those years, and then boarded here, overlooking from afar, with a blue sky, a line of water and sky, and a vast sky. I couldn't help but feel relaxed and happy, and wrote a magnificent poem-"Looking at the Sea".
