Denver sought tenants for Stapleton's terminal and concourses, but these buildings proved ill-suited for alternative uses. A July 1997 hailstorm punched roughly 4,000 holes in the roofs of the old terminal and concourses, causing severe water damage, which compelled the city to tear them down. The airport's 12-story control tower was retained and served for a time as part of the new Punch Bowl Social, a restaurant and social gathering spot. The office building attached to the tower housed the kitchens and social areas; the tower is closed to public access but is available for private tours.
