The Gettysburg Battlefield Historic District is a region of contributing properties and over 1000 historic contributing structures (including Battle of Gettysburg memorials) and 315 historic buildings, most of which are on the protected federal property of the smaller Gettysburg National Military Park. Historic buildings range from a 1776 Colonial tavern to a vacant 1962 Modernist museum. Contributing structures include postbellum artifacts such as the 1895 Big Round Top Observation Tower Foundation Ruin, the 1893 Electric Trolley Bed, and the only remaining Tipton Boundary Marker.
