In the early 17th century, European seafarers came to Asia to trade and develop colonial outposts. In 1624, the Dutch occupied today's Anping and took ten years to build a fort named "Fort Zeelandia." After 1662, because Koxinga and his son lived here, it was named "King Castle," "Anping Castle" as well as "Taiwan Castle." The Japanese rebuilt it and named it "Anping Old Fort." Today, the only Dutch remains are the ruins of a semicircular bulwark and a section of the outer fort's brick wall; the root of an old banyan tree on the wall remains a witness to the fort's long history. Its commanding views of the ocean make it a popular place to watch the sunset. Nevertheless, the fort itself is not that impressing, and neither is the view from the tower during the day. Also, there is not much space in the tower, so it is questionable that many people will be able to enjoy the sunset. Hence, you could skip it for Anping Tree House instead.
