Designed by 'Harvard Five' architect John Johansen in 1970, Stage Center'previously known as Mummer's Theater'is mired in preservation controversy: The prime downtown parcel on which it sits is the envy of developers, while the seminal (though deteriorating) building is the darling of preservationists. Unoccupied since a 2010 flood and now up for sale, the theater's fate hangs in the balance.
