The Lyon Park Historic District is a national historic district and upper-class neighborhood located in Arlington County, Virginia. It was listed on the National Register of Historic Places in 2003.
Location and Boundaries: The district is roughly bounded by 10th Street North to the north, Arlington Boulevard to the east and south, and North Irving Street to the west. It covers an area of approximately 284.4 acres (115.1 ha).
History: The area was originally part of the growing community of Clarendon before becoming a separate neighborhood after 1919, when developer Frank Lyon subdivided a 300-acre tract into 1,200 building lots. Following the success of the first phase, Lyon continued expanding the neighborhood to the east, south, and west, with the final portion platted in 1951.
Architecture: The district contains 1,165 contributing buildings and 1 contributing site. The dwelling styles include a variety of architectural styles, ranging from Craftsman-style bungalows dating from the 1920s to Colonial Revival-style buildings dating from the 1930s and 1940s. A number of Queen Anne style dwellings erected prior to the platting of Lyon Park are also present. Architects associated with the district include Frank Lyon and Walter Sunderland, among others.
