Gulangyu Concert Hall

A museum focusing on the colonial-era foreign residents of Gulangyu, in a building that was once a villa belonging to the Singapore-based OCBC Bank.

Admission is a steep ¥90 for adults, ¥50 for children/seniors, but you can just stand outside and take photos of the Jules Verne-esque octopus statue.

A small gallery of carved calligraphy from Chinese, Japanese, and Korean artists. Entrance near the main gate of Shuzhuang Garden.

This is the highest point on the island with great views as far as Xiamen. Entry included into Buddhist temple, the Aviary and a cable car ride to the aviary on Yingxiong Hill. Warning: climbing to the top involves a lot of stairs, so probably not good for young children or the elderly.
