In the late 19th century, Allegheny, Pennsylvania (later annexed by Pittsburgh), became known for its stately homes, occupied by some of the area's wealthy families. One such area became known as the Mexican War Streets. It developed from land owned by William Robinson Jr., 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, Monterey Street, Palo Alto Street, Resaca Place, Sherman Avenue, and Taylor Avenue. Fremont Street (currently Brighton Place) had been named in recognition of John C. Frémont.
