Glackin Thomas Panzak worked with Easttown Township to develop Hilltop Park. The 25 acre property containing the historic Hilltop Mansion with gardens and a barn was transformed into a public park with the Township’s municipal building. The park entrance leads to a playground area and picnic pavilion. Open hillsides were preserved and landscaped to include trails and athletic fields. The mansion gardens were restored and the barn was converted into the new municipal building.
