Regarding Harmony. National Register Nomination Statement of Significance (excerpt):
The Harmonie Society was one of the most successful of America's many utopian communities. It's high degree of commercialization caused it to play an important role in the commerce and industry of western Pennsylvania. Harmonist manufactures were sold as far away as New Orleans, and their investments in rails, canals, oil fields, lumber, and banks, provided a great stimulus to the local economy. The surviving buildings of Harmony provide a keen insight into the life of this community. Many of the houses have great architectural merit. The Frederick Rapp house with its fine exterior decoration is particularly significant. The proposed historic district will include most of the old town center and insure the preservation of the first home of the Harmonie Society.
