(NPR) XINING, China — The Dongguan Mosque has adopted some very different looks in its nearly 700 years in China’s northwestern city of Xining. Built in the style of a Chinese imperial palace, with tiled roofs and no domes, and adorned with Buddhist symbols, the mosque was nearly destroyed by neglect during political tumult in the early 20th century. In the 1990s, authorities replaced the original ceramic tiles on the roof and minarets with green domes.
