Over the centuries, Taiwan has had to defend itself against the threat of a Japanese invasion, and one reminder of this is the Eternal Golden Castle.
It was built in the late 19th century, and is located near Tainan, the oldest city on the island. One of the most impressive features of the fort is its five meter high gate, along with the walls which in places are two meters thick. Inside, there are several cannons to look at, along with a sculpture of Shen Baozhen, the Chinese general who ordered the fort to be built.
It's located about 30 minutes walk from another attraction, Anping Old Fort.
