The Highmark Mann is a nonprofit performing arts center located in the Centennial District of Philadelphia's West Fairmount Park, built in 1976 as the summer home for the Philadelphia Orchestra. It is the successor in this role to the Robin Hood Dell outdoor amphitheater, where the Philadelphia Orchestra had given summer performances since 1930. Highmark Mann's campus includes an amphitheater, TD Pavilion at Highmark Mann, and a smaller open-air stage, the Skyline Stage at Highmark Mann.
