Shanhaiguan Ancient City, primarily referring to the Shanhai Pass Fort and Dongluocheng, is a well-preserved ancient city in China. The city walls were built using bricks stamped with 11 types of inscriptions, including "Wanli Twelfth Year of the Zhengding Region" and "Wanli Twelfth Year of Luanchuan", making it a valuable historical and cultural heritage.

Among the thousands of dangerous passes along the Great Wall in the Ming Dynasty, the three famous passes of Shanhai, Juyong, and Jiayuguan rank the highest, with Shanhai Pass being the first and largest. Therefore, it is called "The First Pass Under Heaven" for its strategic position and importance as a military stronghold.

The city walls are still well-preserved after hundreds of years, with some sections of the wall being as high as 12 meters. The city walls are surrounded by a deep moat, adding to the city's defensive strength. Inside the city walls, there are many old houses and temples that have been well-preserved, offering a glimpse into the city's rich history.

Visitors to Shanhai Pass can explore the city walls, visit temples and historic houses, and experience traditional Chinese culture. The city walls are open to the public free of charge, but there may be fees for entering some temples or historic houses.

The best time to visit Shanhai Pass is during the day, as most of the attractions are open during the day. The city walls are open all year round, but some temples and historic houses may have specific opening hours. It is recommended to visit during the spring and autumn to avoid extreme temperatures and enjoy pleasant weather for exploring the city.
