We all know that one kid who got really into Jack the Ripper factoids in junior high, was obsessed with Sweeney Todd, and did seances a la Gaby Hoffmann in (the 1995 cult classic) Now and Then. Maybe that kid was you (and may or may not have been me). In honor of Halloween, feed your inner history buff and your paranormal geek at the same time with one (or several) of these spooky local history tours.

Ghost Hunts at the Kreischer Mansion: Explore the Kreischer family home, rumored to be one of the most haunted places in New York. One of the Kreischer heirs committed suicide after a tragic fire destroyed the family’s factory, and his surviving brother repeatedly attempted to contact him via seance. In 2005, the house was the site of a grisly mob murder. Reports of apparitions, disembodied voices, and slamming doors abound. Tours run October 20 & 21 and November 3 and 4. If you're too scared to go yourself, check out our video here.

Advance reservations are strongly recommended.

The exhibition is included in general admission.
