The neighborhood in which the Ambridge Regional Center is located was at
one point in time owned by the Harmony Society. Economy Village, the third
and final home of the Harmony
Society, established in 1824, is located within the current boundaries of
Ambridge.
The Harmonites came to "the promised land" from Germany seeking religious freedom. On a 3,000 acre tract of land, the Society established a large manufacturing center. For a time, this was the leading industial community in the West. The Society with its communal lifestyle, was dissolved in 1905. The history of the neighborhood is very closely woven with those of Old Economy and other surrounding areas. Land owned by the Harmony Society originally included Logstown (near Beaver) and Legionville (located within the present defined neighborhood).
Logstown was the site of an ancient Indian village of great importance in early colonial affairs. It was the Indian metropolis of a large region. In August 1749, Logstown had fifty cabins, which were inhabited by Mohawks, Senecas, Oneidas and Delawares. Legionville came to prominence during
the winter of 1792-1793 when General Anthony Wayne trained "the Legion of the United States". This was probably the first training under the new Federal government. At Legionville he raised the first flag of the United States of America.
