text: The Mexican War Streets were laid out in 1847 by William Robinson Jr., who had earlier been mayor of the city of Allegheny. Robinson, who contrary to some popular tellings did not actually serve in the Mexican War, subdivided his land and named the new streets after the battles and generals (Buena Vista Street, Filson Way, Monterey Street, Palo Alto Street, Resaca Place, Sherman Avenue, Taylor Avenue) of that war.
  Carnegie Free Public Libraries
  Through his foundation matching fund, Andrew Carnegie contributed to the financing and construction of the Carnegie Free Library of Allegheny in Allegheny City.
  St. Anthony Chapel
  Built on Troy Hill between 1880 & 1892 by Father Suitbert Mollinger, the chapel houses the largest collection of religious relics outside of the Vatican and features life sized Stations of the Cross statues.
  Ballparks
  Allegheny was the location of Exposition Park and Recreation Park, which were the earliest home fields of the Pittsburgh Pirates professional baseball team (founded as the Allegheny Base Ball Club). On the North Side of Pittsburgh today are PNC Park, home of the Pittsburgh Pirates, and Acrisure Stadium (formerly Heinz Field), home of the Pittsburgh Steelers. These facilities replaced Three Rivers Stadium, which was the shared home of both teams.
  Felix Brunot Mansion
  The Felix Brunot mansion on Stockton Avenue was once used as a station on the Underground Railroad. Fugitive slaves from the South stopped here for food and shelter. While Pennsylvania was a free state, many slaves continued to Canada to gain more distance from slavecatchers.
