Derry Session House and Enclosure is a historic site located on the grounds of Derry Presbyterian Church at Derry Township, Dauphin County, Pennsylvania. It consists of the log Session House, built about 1732, and a glass enclosure, erected in 1929. The hewn log Session House measures 18 feet by 13 feet and is one story high and was built for a Presbyterian session. The glass and steel enclosure measures approximately 24 feet by 19 feet, 6 inches, and sits on a reinforced concrete foundation. The Enclosure, whose construction was originally funded by Milton S. Hershey, was refurbished in 1999.[2]
It was added to the National Register of Historic Places in 2006.
