View of Panther Hollow Lake. Located in Schenley Park, Panther Hollow Lake is a manmade lake built in 1909. Stretching over the lake is the Panther Hollow Bridge. The bridge was designed by Henry B. Rust and erected in 1897. The main span of the bridge is 360 feet long and the deck is 120 feet high. The nearby Schenley Bridge, also constructed in 1897, is nearly identical to Panther Hollow. One of the main distinguishing features about Panther Hollow Bridge are the four bronze panthers designed by Giuseppe Moretti, located at each corner of the bridge.
