In the mid-19th century, Xiamen became an international trading port, and many foreigners settled on the island of Gulangyu, leading to the construction of a variety of European-style villas and foreign consulates. The return of affluent locals from abroad added more residence styles to the mix. Most distinctive is the red-roofed Eight Diagrams Tower, built in 1907 by Lin Heshou, then one of the richest men in Taiwan. It combines the styles of Jerusalem mosques, ancient Greek temples and classical Chinese architecture, and houses the Organ Museum, which has a six-metre-long Norman & Beard pipe organ.
