The centre, Tàng Thơ Lâu, was built in 1825 under Emperor Minh Mạng (1820-1841) by 1,000 soldiers. Its overall architecture was designed to store and preserve important books, documents and papers of the court. The building is located on a rectangular island in the middle of Học Hải Lake, which is connected to the mainland by a bridge built of bricks and stones on the west bank.
