The Little Church at Keystone, on McGinley Street in Keystone, was built in 1907–08 by carpenter Ed Casey of Red Oak, Iowa, and is attributed to Omaha architect Thomas R. Kimball. Because the town was too small for two churches, it has a Catholic altar at one end and a Protestant lectern at the other, and the pew backs flip to face either way. It was dedicated on August 16, 1908, and is listed on the National Register as the Keystone Community Church. Admission is free; call (308) 726-2006 or (308) 726-2281 for a tour.
