Biohazard Cleanup Near North Harmony Harmony, PA

Harmony is a borough in Butler County, about 30 miles north of Pittsburgh, that was founded in 1804 by German religious leader Johann Georg Rapp and his followers.

Harmony was the first home of the Harmony Society, a communal religious group that formally organized on February 15, 1805, holding all property in common.

Harmony's Harmonists built a thriving commune of some 100 buildings, including a church, school, woolen and grist mills, a brewery, and a tannery, and the town soon numbered around a thousand members.

Harmony was sold by the Harmonists in 1814 to a Mennonite group led by Abraham Ziegler, after which the Society moved west to found New Harmony, Indiana, and later returned to Pennsylvania to build Economy, now part of Ambridge.

Harmony is designated a National Historic Landmark district, and the Harmony Museum preserves nine historic properties covering more than 250 years of local history.

Harmony was incorporated as a borough in 1838, after the Mennonite era began.

Harmony had a population of 942 at the 2020 census.

Harmony had about 890 residents living in 389 occupied homes at the 2010 census.

Harmony covers only about 0.39 square miles in the valley of Connoquenessing Creek, next to the borough of Zelienople.

Harmony students attend schools in the Seneca Valley School District.
