Mount Lao is nearly as famous as the province's other famous mountain, Mount Tai. It is known as one of the birthplaces of Taoism, a place of pilgrimage for centuries. Mount Lao once had 9 palaces, 8 temples, and 72 convents. Many of these places have been lost over the years, but a number of the temples remaining are worth a look for their elegant architecture and their excellent views out to sea. With sheer cliffs and cascading waterfalls, the beautiful mountain is widely recognised in China as a source of the country's best-known mineral water (a vital ingredient in the local brew, Tsingtao). At the peak of Taoism, there were nine palaces, eight Taoist temples, and 72 nunneries that housed nearly 1,000 Taoist priests and nuns on the mountain. At present, the Taiqing Palace is the largest and oldest among the preserved Taoist establishments. First built in the early Northern Song Dynasty (960-1127), the palace has a history of nearly 1,000 years and features a simple architectural style.
