It is hard to choose; there are so many. Something that most graduates have never seen was the Drill Hall. An artifact of the Second World War, it was the centre of many activities during my time at McMaster. Most indoor sports (bridge was played at the Rec. Hut) were played there. Dances, including the Formals (I remember Mart Kenney playing for one) were held there. Because it was the only building large enough to hold all 990 students, all final exams were written there. It was one centre of campus life in those days.
