“Lacey Lane” and “Manx Lane” are two private lanes in the Sandy Hill neighborhood of Northeast Washington, D.C. The lanes are named after two of the neighborhood’s original landowners, Colonel John Lacey and Thomas Manx. Lacey Lane runs north-south between Blagden Avenue and Rittenhouse Street, while Manx Lane runs east-west between 13th and 14th Streets NE. Both lanes are narrow and lined with historic homes, making them popular destinations for walkers and tourists.

Lacey Lane and Manx Lane are significant because they are two of the few remaining examples of private lanes in Washington, D.C. Private lanes were once common in the city, but most have been closed or converted to public streets over the years. Lacey Lane and Manx Lane are also important because they are part of the Sandy Hill Historic District, which was designated in 1989. The historic district includes over 400 buildings, most of which were built in the late 19th and early 20th centuries.
