Airy neighborhood of Philadelphia, Pennsylvania. It was built in 1928 and designed by architect William Harold Lee. It is one of the remaining 20 Philadelphia theaters as of 2006[update] which he designed; nine have been demolished. Only two in Philadelphia are open- The Ace Theater (Holiday Art Theater) and The Sedgwick Theater. Just outside Philadelphia, two more of Lee's theaters are seeing restorations: the Bryn Mawr and the Hiway Theater in Jenkintown.
