Mexican War Streets

The Mexican War Streets, originally known as the "Buena Vista Tract," is a historic district that is located in the Central Northside neighborhood of Pittsburgh, Pennsylvania, in the United States. The district is densely filled with restored row houses, community gardens, and tree-lined streets and alleyways. The area dates to around the time of the Mexican–American War.

Brief history
During the late nineteenth century, Allegheny, Pennsylvania (later annexed by Pittsburgh), became known for its stately homes that were occupied by some of the area's wealthy families. One such area became known as the Mexican War Streets. It was developed from land owned by William Robinson Jr., an ex-mayor of the city of Allegheny, who subdivided the property into streets and lots in 1847. Surveys for the development were made by Alexander Hays.

A number of the streets are named after battles and generals of the Mexican–American War, including Buena Vista Street (named for the Battle of Buena Vista), Monterey Street (for the Battle of Monterrey), Palo Alto Street (for the Battle of Palo Alto), Resaca Place (for the Battle of Resaca de la Palma), Sherman Avenue (for Thomas W. Sherman), and Taylor Avenue (for Zachary Taylor). Fremont Street (currently Brighton Place) had been named in recognition of John C. Frémont.

Historic district designation
The 27 acre district was listed on the National Register of Historic Places in 1975 with 119 buildings deemed to contribute to the historic character of the district. In 2008, the district's listing was increased to include an additional 288 contributing buildings over a 25.7 acre area. It was expanded again in 2018, when the Allegheny County Court of Common Pleas overturned the decision of the Pittsburgh City Council to deny the district's expansion.

The general boundaries of the Mexican War Streets Historic District are Brighton Road to Federal Street (on the east and west) and North Avenue to Jefferson Street (on the south and north). As part of the designation, all exterior alterations to buildings within the Historic District that are visible from a public street or way must be reviewed and approved by the City of Pittsburgh's Historic Review Commission.
