The Crystal Palace in Picton, Ont., was broken into earlier this week, OPP say.
On Sunday morning, police say they received a report of a break and enter at the historic building on Main Street.
Police say that some windows and doors of the structure were smashed in order to gain entry.
OPP say there is nothing to steal inside the Crystal Palace at this time, so they are unclear on the motive of the break-in.
Prince Edward County OPP are asking for help from the public to identify those responsible. They ask anyone with information to contact OPP at 1-888-310-1122.
