The most eye-catching building inside the gates of National University of Tainan is the main building of the former Tainan Teachers College, officially named Office of the Taiwan Governor General Tainan Teachers College at the time. Towards the end of World War II, the roof was almost totally destroyed by missles in an air raid and was only repaired in 1947. The building has a double-crucifix shape and was built mainly using red bricks, which is why it was known as the “red building.” There is an Okinawa Pine in front; it is said to have been planted by future Emperor Hirohito when he visited Tainan in 1923 as Crown Prince; together with the “red building,” it is a symbol of the university. June-July every year, the golden shower trees around the building bloom, their cascade of golden flowers and the red brick of the building complementing each other. This is the best season to visit.
