The hidden room, discovered by a demolition crew during Memorial Day weekend, remains a talker in Middletown.
Richard Olszewski was operating the excavator when someone spotted the room. Crews went inside and discovered a room that leads to a tunnel.
Olszewski says they will not resume demolition until they get the word. "The property owner suggested I hold off," said Olszewski.
Donna Weber lives next door to the star attraction on Ann Street. She says it reminds her of Grand Central Station.
According to Weber, police have been warning people not to go inside and they have been writing citations.
Some historians say there is the possibility the property was a safe heaven for slaves as they made their way across the underground railroad, while others have said the home was a speak easy during prohibition.
An official with the Pennsylvania Museum Commission says the property may have been built in the 1870's as a saloon, and the hidden room could have been used as a cold storage.
