[3] The town is near the location of Legionville, the training camp for General "Mad" Anthony Wayne's Legion of the United States.

Wayne's was the first attempt to provide basic training for regular U.S. Army recruits and Legionville was the first facility established expressly for this purpose.

The society was dissolved and its vast real estate holdings sold, much of it to the American Bridge Company, who subsequently enlarged the town and incorporated it as Ambridge in 1905.

In addition, many of the ethnicities had their own church, club, and musical group that sought to give immigrants a familiar place to be as well as to preserve their culture.

Many were from Eastern and Southern Europe including Italian, Greek, Slovak, Croatian, Ukrainian, Polish, Slovene, and Carpartho-Rusyn, to name a few.

During World War II, the American Bridge Company fabricated steel for the building of LSTs (Landing Ship Tanks).

The decline of both the steel industry and the town is chronicled in Rust Belt Boy by Ambridge native Paul Hertneky.

Ambridge has two land borders, including Harmony Township to the north, east and northeast, and the Allegheny County borough of Leetsdale to the southwest.

The city of Aliquippa runs adjacent to Ambridge across the Ohio River to the west and is connected to the borough via Ambridge-Aliquippa Bridge.

Organized by the Ambridge Chamber of Commerce, the three-day Nationality Days festival takes place in May and is located in the heart of the downtown Commercial District.

Vendors line the center of Merchant Street as thousands of attendees – locals and tourists – enjoy Italian, Ukrainian, Greek, Polish, German, Croatian, and Slovenian cuisine.

Booths are sponsored by numerous churches in Ambridge, bringing with them the recipes for their cultural dishes such as pirohy, haluski, stuffed cabbage, and borscht.

Established in 1824, Old Economy - known to the Harmonites as "Ökonomie" - was founded upon German Pietism, which called for a higher level of purity within Christianity.
