to 120 people, and three Dormitories each sleeping 36–40. Camp Greene, a former Girl Scout Camp which added about 30 acres to The Glen in 2015, offers a 1920s era lodge which can accommodate up to 200 people, as well as dormitory facilities. Birch Manor is a 1931 Georgian-style mansion designed by architect William Shilling. It was home to Hugh Taylor Birch, the benefactor who two years previous had donated the initial 700 acres for the preserve, and Birch lived there seasonally for a decade before dying at age 94. As originally built the house had 11 rooms, nine bathrooms, eight fireplaces, and a garage with servant's quarters. However, when Antioch College President James Dixon lived there, he added additional rooms, bringing the total up to 18. The space is suitable for up to 150 people outdoors or 110 people indoors. Many of the Glen Helen facilities, including the Vernet Ecological Center, the Outdoor Education Center Lodge and Dormitories, Camp Green, Birch Manor, and even a meadow, are rentable event venues available for special functions. The Riding Centre, a therapeutic equestrian facility, is physically located on land leased from Glen Helen, but is operated separately.
