The Black Dragon Cave is in fact an ancient temple complex located on Zhonghe Mountain to the east of Zhenyuan Ancient Town and covers an area of some 21,000 square meters (approximately 226,050 square feet), and is the centerpiece of the all ancient monuments in Zhenyuan. The the Black Dragon Cave Temple as it is also known includes single and multi-storied pavilions, temples, shrines, palaces and so on. Surviving a couple of wars, the Black Dragon Cave was built during the Ming Dynasty (1368-1644) and its current shape is the result of several renovations.

With many separate buildings, the Black Dragon Cave encompasses Zhusheng Qiao (Zhusheng Bridge), Zhongyuan Temple, Ziyang Shuyuan (academy of classical learning), Yuhuang Ge (Jade Emperor Pavilion), Longevity Palace, Xianglu Yan. Among the ancient complexes of Zhenyuan, the Black Dragon Cave though very close to the town has retained its natural flavor.

All of the buildings there were constructed in accordance with the natural features of Zhonghe Mountain which is precipitous. The architectural sculptures and adornments there are simple and unsophisticated and yet quietly elegant, and are quite unlike those of other temples which are ornately decorated. The way in which these Confucianist, Taoist and Buddhist temples are arranged together embodies the combination of Taoism, Buddhism and Confucianism in a way. One renowned architect once remarked that the Black Dragon Cave won the upper hand over the famous Hanging Monastery in Shanxi Province in terms of architectural art.

Against the green backdrop, the Black Dragon Cave seems to cling to the mountainside in an orderly tiered way due to the precipitous cliff, which makes it blend the characteristics of a garden with the style of a temple.

In 1988, the Black Dragon Cave was listed as a key cultural relic under state protection.
