Tsai Yuan-Pei Memorial Hall was originally planned to be used as a Scholar Residence. It was constructed during President Hu Shih's tenure and opened in 1960. It underwent renovation in 2012, with the first floor now serving as a multifunctional lecture hall, archive, and restaurant, while the second floor is currently used as office space for the Department of Legal Affairs.
