DALLAS TWP. — Kathy Barlow is heartbroken about that the Himmler Theater will be demolished. The red-brick theater at 48 Lake St. has been shuttered for nearly five decades. On Thursday, it will be reduced to rubble along with properties located at 24, 30, 32 Lake St. Misericordia University owns the four properties, according to Mark Van Etten, vice president of finance and administration at Misericordia University. Plans for the spaces include “a pocket park with matching downtown pathway lighting, sidewalks, green spaces,” a parking area, which extends behind the Old House Café at 34 Lake St.
