Penn Park is a 24-acre (97,000 m2) park on the campus of the University of Pennsylvania in Philadelphia, Pennsylvania. The park is at South 31st Street and Walnut Street, and features two athletic fields, a multipurpose stadium with 470 seats, a tennis center, a seasonal air structure, and picnic areas.[1][2] In Fall 2014, Penn partnered with the Philadelphia Orchard Project to establish the Penn Park Orchard in the southeastern corner of the park.[3]
