The Friends of Abolition Hall have argued that the townhouse project would destroy the integrity of one of Pennsylvania's most significant historic sites. The 10-acre Corson property, at Germantown and Butler Pikes in the village of Plymouth Meeting, was a hotbed of the antislavery movement during the first half of the 19th century. The farm's owner, George Corson, was a committed abolitionist who provided escaping slaves with a safe refuge and turned his barn into a lecture hall for antislavery rallies. Speeches by people such as Frederick Douglass and Lucretia A. Mott attracted so many people that the barn became known as Abolition Hall.
