The L'Enfant Trust is a 501(c)(3), non-profit organization founded in 1978 to preserve and revitalize DC's historic communities. The Trust has a range of historic preservation programs, including education and outreach activities. The Trust's main programs are its nationally recognized conservation easement program, which protects more than 1,130 of Washington's historic structures from demolition or inappropriate modifications, and its revolving fund program, through which the Trust acquires and rehabilitates distressed historic buildings where such rehabilitation will have a positive impact on community revitalization.
