The westside campus is located on land purchased in 1969 on the outskirts of Danbury. This lot is home to the Ancell School of Business, the School of Visual and Performing Arts, the Westside Nature Preserve, an amphitheater and three residence halls. Westside also houses athletic facilities, including the William O'Neill Athletic and Convocation Center (completed in 1995), and the Westside Athletic Complex (completed in 2003), as well as an observatory with a 20-inch Ritchy-Chretien telescope and a 20-foot planetarium dome. On January 23, 2007, the Westside Campus Center was officially opened. This new facility serves as a student center, meeting and banquet facility for the Westside campus. In August 2014, the Westside campus saw the opening of the new Visual and Performing Arts Center, a comprehensive arts building with Theatre Arts, Music and Visual Arts wings.
