The rebuilt Southwest featured a large concentration of office and residential buildings in the brutalist style that was then popular. It was during this time that most of the Southwest Federal Center was built. The heart of the urban renewal of the Southwest Waterfront was Waterside Mall, a small shopping center and office complex, which housed satellite offices for the United States Environmental Protection Agency. The Arena Stage was built a block west of the Mall, and a number of hotels and restaurants were built on the riverfront to attract tourists. Southeastern University, a very small college that had been chartered in 1937, also established itself as an important institution in the area.
