Through a $30 million renovation funded partly by the state, the 36,000-square-foot Baptist Temple at Broad and Berks Streets in North Philadelphia will shake off its dust and take in a breath of new air. The 119-year-old building has been transformed into a grand multipurpose center to be used by the university and community for concerts, presentations, and other performances. It will be the flagship in the effort to extend the Avenue of the Arts north on Broad Street, said Charles Bethea, executive director of the Baptist Temple.
