History
Sligo Creek was named after the crossroads named "Sligo" founded in the mid 19th century by
Irish immigrant workers on the
C&O Canal. It may have been named after
County Sligo in Ireland. The crossroads was located at Colesville Road and the
7th Street Pike

, Sligo had a toll gate on the 7th Street Pike, an inn and a post office. A half mile from the Sligo crossroads Colesville Road crosses Sligo Creek. NOTE: "SLEGOE" was the name of a part of the tract of land titled "Charles and William" lying in the encompassed area that became the Village of SLIGO, owned by the BEALL, BADEN and CLARK families. First mention of and identified as "SLEGOE" is found in 17th and 18th century Land Records recorded in Prince George's County and later, Montgomery County, Maryland.
Over the years, Sligo Creek has served many purposes for area residents, including powering grist mills and as a

, the earliest public water system in the area, served the city of Takoma Park. The water system was sold to the
Washington Suburban Sanitary Commission in 1919, which abandoned the facility in 1930.
Another dam, located where Flower Avenue crosses Sligo Creek, served Sligo Mill which was located where the current
New Hampshire Avenue crosses Sligo Creek. Sligo Mill was built in 1812 by investors that included several members of the prominent Maryland
Carroll family. In addition to milling grain for local farmers, Sligo Mill distilled
whiskey
Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden c ...
. The mill was demolished in the 1920s.
Overlooking the dam and millpond for Sligo Mill on the right bank of Sligo Creek, the Glen Sligo Hotel and Wildwood Amusement Park were built in 1900. The hotel and amusement park ceased operations in 1903.
Sligo Creek served as the inspiration and title for "Sligo River Blues", a song by
Takoma Park guitarist
John Fahey, who popularized the area amongst folk artists. It also inspired "Sligo Creek," an Irish traditional reel composed by an American banjo, mandolin, fiddle and guitar player Danny Noveck, who lived near the creek at the time he composed the melody. Another prominent folk guitarist,
Al Petteway, composed "Sligo Creek" while living in the Takoma Park area. This Scots-influenced guitar tune was later featured as the theme song of ''
The National Parks'', a PBS miniseries directed by
