The 16-acre Montrose Park sits adjacent to Dumbarton Oaks and above Dumbarton Oaks Park on a sloping hillside at 30th and R Streets, on the north side of the Georgetown neighborhood of Washington, DC. The land was obtained between 1804 and 1813 by Robert Parrott, a 19th-century industrialist who owned the Georgetown Wool & Cotton Factory, and manufactured rope at a ropewalk that he constructed on the grounds. Parrott built a house on the property, named Elderslie. The estate was known as Parrott’s Woods by locals who were allowed to use the grounds for picnics and other leisure activities. After Parrott’s death in 1822 the property passed through several different owners and eventually came to be known as The Montrose Estate. In 1902, Georgetown resident Sarah Louise Rittenhouse led a group of women to petition Congress to purchase the estate as parkland, thus preventing its commercial development. Congress passed a bill on June 25, 1910, and the estate was officially purchased in 1911 for $110,000.00. The park, designed by George Burnap  at the office of Public Buildings and Grounds, includes tennis courts, trails, a playground, a boxwood maze, woodlands and the original ropewalk. In 1956 a commemorative monument was dedicated to Rittenhouse at the entrance of the park. The park is currently administered by the National Park Service as part of the Rock Creek Park system and is listed in the National Register of Historic Places as part of the Georgetown Historic District.
