It is the location of the Ardsley SEPTA station.On December 7, 1777, the Battle of Edge Hill was fought in the area. British forces attacked American troops posted on Edge Hill, which runs from southwest to northeast along the present-day Willow Grove Avenue and Edge Hill Road. Near where Limekiln Pike crosses Edge Hill, British and Hessian light infantry routed a force of Pennsylvania militia and the 2nd Connecticut Regiment led by Joseph Reed. Farther to the northeast on Edge Hill, riflemen and Maryland militia commanded by Daniel Morgan put up a tougher fight before falling back to join the main army at Camp Hill and Fort Washington.In 2001, the area was heavily damaged by Tropical Storm Allison. A township project was undertaken to stop future flooding. This project included the re-creation of a drainage basin known locally as "Floaties Pond", which has worked well in that not much more flooding has occurred.
