After a year of remodeling and restoration, Rick Hetzel and Cheryl Mothes, the owners of the Kage School, will be hosting an open house Sunday to showcase their two-bedroom, fully furnished guest cottage, which soon will be available for rent. The open house is scheduled to take place from 2 to 5 p.m. at the old schoolhouse at 3110 Kage Road. The school, built in 1880 and closed in 1966, was listed on the National Register of Historic Places in 2005. The school hereafter will be known as the Historic Kage School Guest Cottage. A flag-raising ceremony marked the re-opening Wednesday morning, with the previous owner’s grandson, Davis Deimund doing the honors. Hetzel said rehabilitating the one-room schoolhouse required extensive interior and exterior repairs because of termite and water damage over the past 50 years.
