The oldest commercial district and the original center of Bala Cynwyd straddles the bridge over the old Pennsylvania Railroad tracks, originally belonging to the Columbia Railroad and now part of the SEPTA Cynwyd Line, along Montgomery Avenue at Bala Avenue. This district, long on the National Register of Historic Places, was settled shortly after William Penn's landing in Pennsylvania in 1682 and contains the village's oldest commercial buildings, some dating to the earliest years of the 19th century. Bala Avenue itself is an extension of this original town center and comprises a specialized commercial district of its own more than a century old; it has long been known for its children's clothing stores, women's dress and consignment shops, the Bala Theater and a number of small restaurants. The remainder of Bala Cynwyd's original commercial district extends south along Montgomery Avenue as part of the Bala Cynwyd-Merion Commercial District and is coextensive with the commercial center of Merion, with its popular delicatessens and restaurants.
