The Mason County Courthouse is an impressive structure that has intrigued me since I was a young boy. Our courthouse was finished in 1894 and is still in use today. Grand Rapids architect Sidney J. Osgood designed the Richardsonian Romanesque building. The sandstone used to build the courthouse came from the Upper Peninsula of Michigan. F5.0 at 1/320, ISO 100, 18-50 mm lens at 23 mm
