Introduction to the Tuen Barracks Site: The Tun Barracks was a place where the soldiers who defended the new city lived. It has two specifications: three bays and double rooms inside and outside. The doors all face south, and the architectural form is a ground-type wooden structure. In 2004, archaeological excavations unearthed a large number of house foundations and discovered architectural remains such as stoves, pillar holes, and drainage ditches.
