PHILADELPHIA, PA – Tucked away on the grounds of the Philadelphia Zoo stands The Solitude, a historic 1784 mansion built for William Penn's grandson that is generally accepted by Zoo staff to be haunted. Access to this landmark is extremely rare, but this summer, the Zoo is offering a unique opportunity to get inside—if you can solve a murder first.
The grand prize for the Zoo's second annual after-hours mystery night, "Zoo Done It?" on Saturday, August 2, 2025, is an exclusive, private guided tour of The Solitude during the "spooky season" this fall. This is the only opportunity for the public to gain such exclusive access to the historic and reputedly haunted building.
The Haunting of The Solitude
Built for John Penn as an escape from the city, The Solitude has a long history of strange occurrences reported by Zoo staff. The most common event involves a mysterious light in the attic, which often turns on by itself late at night and sometimes remains lit until morning. The historic landmark has been covered by media and television programs from around the world for its paranormal lore.
"This is the only time we give the public a chance to get exclusive access to The Solitude, a famous American historical landmark," said Patrick McMaster, the Zoo's Vice President of Marketing and Communication.
