Summer Seat was formerly a local landmark, Reilly's Summer Seat Farm. Up until 2015 it was open to the public for “pick-your-own” crops of strawberries and pumpkins. The land has a rich history as part of Pennsylvania’s Depreciation Lands: 720,000 acres granted to Revolutionary War soldiers for their services. A 334-acre parcel was granted to soldier Richard Sommers on July 6, 1786, titled "Summer Seat" on the original deed. In 1819, Irish immigrants, the O'Neils, purchased the property, and farmed here continuously for four generations. In 1941, the Reilly family purchased the original homestead and 37 adjoining acres in order to raise their children in the country. It became a working farm again when one of their children took over the property in 1983. The Reillys sold the property to Traditions of America in 2015 and the first homes were completed in the spring of 2017.
