More than half a century after the three Century Theater domes—21, 22 and 23—opened on Winchester Boulevard, their lease is up and the future is uncertain. While an eyesore for some, the grey-capped structures inspire nostalgia for others. Preservationists who appreciate the buildings for their unique, retro-futuristic architecture have fought to garner a historical designation for at least one dome. Signatures are being collected through Change.org, and the petition goes before the city in April. But by the end of the month, the theaters will close.
