Back for the fourth year, Michigan City’s Barker Mansion is hosting Blackout Tours this month. The tours offer a different look at the mansion: one viewed in near darkness. During the event, tea lights and glow stick necklaces, worn by guests, are the only sources of illumination. Guests are led through the mansion by staff who tell stories of unusual and eerie historic happenings, taking place both at the mansion and throughout Northwest Indiana. The tours were conceived by Heritage Interpreter TJ Kalin in 2016, now serving as Assistant Director. The idea came to him as he realized that many of the mansion’s tour guests wanted to know what happens behind the scenes, when all the lights are off. Advance reservations are required for the tours, which typically sell out in advance; walk-ups are not permitted. Tours will be offered on October 18, 19, 25 and 26. Two time slots are available: an 8 pm Central Time tour is geared toward families, and a 10 pm tour is for adults only. Tickets cost $15 per adult and $10 per youth and are available on Eventbrite or by calling the mansion at (219) 873-1520 x5.
