This grand neo-classical structure constructed in 1902 has been home to many transmutations, including the former corn exchange bank and the home for promiscuous 20-something realibrities on MTV’s “The Real World – Philadelphia.” Now it stars principally as a private event space, for which its stately columns, stark Italian marble, towering ceilings, intimidating chandeliers and mezzanine that’s all the better to see you from, my dear, make it a fairytale setting. Rotating art exhibitions by emerging artists encourage easy ice-breaker conversation, whether guests are attending the half-million dollar wedding of a Main Line princess or a mod, ticketed, DJ-hosted fete.
