Historic Washington State Park

Historic Washington State Park (formerly Old Washington Historic State Park) is a 101-acre (41 ha) Arkansas state park in Hempstead County, Arkansas in the United States. The museum village contains a collection of pioneer artifacts from the town of Washington, Arkansas, which is a former pioneer settlement along the Southwest Trail. Walking interpretive tours are available throughout the 54 buildings. Washington served as a major trading point along the Southwest Trail, evolving into the Hempstead county seat and later the capital of Arkansas from 1863 to 1865 when Little Rock was threatened during the Civil War. The original plat of Washington was added to the National Register of Historic Places in 1972 as the Washington Historic District.

During the 1820s and 1830s, Washington was a stopover for travelers going to Texas. It was originally the county seat of Hempstead County until a new courthouse was completed in Hope, which was designated the seat of government in 1939. The park emphasizes regional 19th century history from 1824 to 1889. It is located in southwestern Arkansas east of Texarkana and near the entrance to Interstate 30.
