Frick Park is the largest municipal park in Pittsburgh, Pennsylvania, covering 644 acres (1.006 sq mi). It is one of Pittsburgh's four historic large parks. The park began when Henry Clay Frick, upon his death in 1919, bequeathed 151 acres (0.236 sq mi) south of Clayton, his Point Breeze mansion (which is now part of the Frick Art & Historical Center). He also arranged for a $2 million trust fund ($29.9 million today) for long-term maintenance for the park, which opened on June 25, 1927. He did this against his will, but rather acquiesced to his daughter, Helen's debutante wish which he had promised to honor.
