The Chikan Tower is the oldest building in Tainan and one of its most important tourist attractions. It was originally built in 1652 AD by the Dutch, and then underwent many repairs and renovations over the past 300 years to give it its current exterior. Inside there is a temple, pavilion, and college, and outside stands a distinctive colossal statue. One of the most striking things is the nine imperial bases at the south gate carried by the stone. The tower is surrounded by yellow lighting, adding an ancient charm to the building. Concerts are often held in the square in front of the building, making it a very popular nighttime destination among Tainan residents.
