Arnold is a city in Westmoreland County, Pennsylvania, United States, within the Pittsburgh metropolitan area. The population was 5,157 at the 2010 Census.


Present-day Westmoreland County was part of the hunting reserves of the Iroquois Indians. White colonists began to penetrate the area in the 1750s, and circa 1781 Robert McCrea purchased the land on which Arnold is situated. William Jack acquired the property and later passed it on to Wilson Jack. The area around Arnold was first settled in 1852 by Major Andrew Arnold, who grew up in Kittanning.

Arnold was part of New Kensington until it was separately incorporated as a borough in January 1896, and as a third-class city in 1939. Arnold is governed under Pennsylvania's third-class city code, with a mayor and four council members elected at-large. Past mayors of Arnold have been M. Frank Horne (1939-1960), Alfred Colaianni (1960-1963), Willie DeMao (1963-2004), John Campbell (2004-2012), and Larry Milito (2012-2016).

The current mayor, Karen Peconi-Biriccochi, a Democrat, took office in 2016. While in office due to protests in reaction to the killing of an unarmed African-American teen Antwon Rose by a white police officer in East Pittsburgh, Mayor Peconi urged law enforcement to "bring the hoses" against the protesters. She later apologized, however, faces calls for her resignation. [3]

Notable landmarks in Arnold have included:

  • Arnold Station, established in 1867, which was Arnold’s railroad stop. It was so named because the land on which it was built was given by the Arnold Family.[7]
  • The Chambers Glass Company, which opened in 1891, was at the time the first, best equipped, and most efficient glass plant in the country.[7]
  • George Moore Home, which was built with 17 rooms, but has since been demolished.
  • The Morris Davis home stands across from where the George Moore home stood. Morris Davis built it very precisely, rejecting many loads of lumber if they had knotholes or any defects. It was one of the very first homes in the area that had electricity.
  • The Hartley Howard Home was another home of that time, which still stands today, serving as apartments.
  • Eiler Hall was a fashionable site for parties, dances, banquets and public shows. It is now a parking lot for city employees of the Municipal Building.
  • The Edna Hotel was named after George Moore‘s daughter Edna in the late 1800s. It was the meeting place for all of Arnold at the turn of the 20th century. The building was destroyed by a massive fire in the late 1990s and is now a vacant grass lot.
  • The John Fedan Store began as a rental for other merchants. When that did not follow through, Fedan started his own business with a small hardware store and later added a furniture and appliance store.
  • The Arnold Drug Store opened in 1898 and was also the post office location at the time.


Arnold is served by the New Kensington–Arnold School District, which includes four schools in New Kensington and Arnold: Valley Jr/Sr High School, three elementary schools. Roy A. Hunt Elementary (Arnold), H.D. Berkey School (Arnold), and Martin Elementary School (New Kensington).

The current Roy A. Hunt Elementary once served as Arnold's high school prior to the merger of the two districts. After the merge was completed it was used as Valley Middle School until the restructuring of the school district at the end of 2012, and now stands as an elementary school holding grades 3-6
