Greenfield is a member of Pittsburgh's 15th Ward, which includes the neighborhoods of Greenfield and Four Mile Run. Greenfield is adjacent to the Pittsburgh neighborhoods of Hazelwood to the south, Oakland and Schenley Park to the north, and Squirrel Hill to the east. Pittsburgh Fire Station #12 is located on Winterburn Avenue in the neighborhood.
In 1758, a large tract of woodland was purchased for $10,000 under the Treaty of Fort Stanwix made with the Native-Americans. This area included what became Greenfield and neighboring Hazelwood, which today are both part of the city's 15th ward. By the late 1800s, many of Greenfield's residents were of Irish, Polish, Slovak, Italian, Hungarian, and Carpatho-Rusyn descent. They resided in Greenfield and traveled to Hazelwood, Homestead and Duquesne to work in the steel mills.
Points of interest
Greenfield contains two small business districts along Greenfield Avenue and Murray Avenue. A major travel route is along Beechwood Boulevard, connecting I-376 to the Waterfront shopping district in Homestead. As a predominantly residential neighborhood, Greenfield boasts three baseball fields, four basketball courts, two hockey rinks, two soccer fields, and a swimming pool. It is also home to seven churches and one synagogue; the largest is St. Rosalia, a Roman Catholic church. Greenfield is known among locals for very steep hills, a chaotic street grid off the main roads, and a preponderance of single lane 2-way streets, which does not usually lead to congestion as the neighborhood is not heavily traveled (excluding Murray and Greenfield Avenues and Beechwood Boulevard, which are all multi-lane streets).
Similar to other Pittsburgh neighborhoods, Greenfield hosts a holiday parade and fireworks every December. The fireworks, which are usually sponsored by Zambelli Fireworks, are shot off from Magee Field.
