Two more properties in Grand Forks have been listed on the National Register of Historic Places.
The register is the federal government's list of properties deemed worthy of recognition and preservation.
The Grand Forks Herald reports that the Skarsbo apartments and the Hariman Sanatorium both were built in the late 1920s.
The Skarsbo buildings still function as residences. The sanatorium began as a chiropractic hospital and has been converted into apartments.
