Located at the heart of the oldest area on Tsinghua campus is the imposing auditorium. Mixing Greek and Roman architectural styles, the 1,200-seat auditorium has a rounded roof, a brass gate, and four large white marble columns. It possesses few design embellishments; its magnificence is evident in its simplicity.

　 Construction on what is now one of the favorite buildings on campus began in September 1917 and concluded in March 1920. The auditorium was one of the four major building projects carried out by Tsinghua School, together with Tsinghua Xuetang, the old library, and the gymnasium.

　 In its day, it was the largest auditorium of its kind at a university in China, and could seat the entire faculty, staff and student body for school assemblies.
