大礼堂是清华早期“四大建筑”之一，建成时是国内高校中最大的礼堂。大礼堂的建筑具有意大利文艺复兴时期的古罗马和古希腊艺术风格，罗马风格的穹隆主体，开敞的大跨结构，汉白玉的爱奥尼克柱式门廊。整个建筑下方上圆，庄严雄伟，象征着清华人"坚定朴实、不屈不挠"，是清华的集会中心。现在校内的会议、讲座及娱乐演出，仍经常在此进行。

Tsinghua’s Auditorium used to be the largest auditorium cum lecture theatre among all universities in China. Together with the old library, the science building and the gymnasium, the auditorium is also famously known as the Four Buildings of Early Tsinghua. The auditorium housed 882 seats, is currently  the  most  popular venue for cultural forums,  important meetings,  faculty activities and movie screenings on campus.
