It was at this site during the winter of 1805-1806 (December 8-March 6) that the Lewis and Clark Expedition made their last encampment on their journey to the Pacific Ocean. They built a fort and named it Fort Clatsop after the Clatsop Indians who lived in the area. The structure seen today was built in 2005 after the first one, which was built in 1955, was damaged in a fire. The weather and time eventually destroyed the original fort. The site is located in the Lewis and Clark National Historical Park (to which other nearby parks belong), which is a National Historic Landmark. The Fort Clatsop site is listed on the National Register of Historic Places.
