Longstreet Tower (No. 2 of five at Gettysburg) was built on the ridge by the War Department in 1895. West Confederate Avenue was built at the turn of the 20th century for Seminary Ridge tourism, while Sharpshooters Avenue (named Berdan Avenue by 1930) was extended from W Confederate Avenue in 1917 for access to a Pitzer Woods monument. In 1918, various military camp sites (e.g., Camp Colt) were located in the "Field of Pickett's Charge" between the Seminary and Cemetery ridges. The North Carolina Monument was placed on the ridge in 1929.
