Celebrating 40 Years of the Historic Landmark and Historic District Protection Act of 1978!
In December 1978, the Council of the District of Columbia and Mayor Walter Washington declared as a matter of public policy that the protection, enhancement and perpetuation of properties of historical, cultural and aesthetic merit are in the interests of the health, prosperity and welfare of the people of the District of Columbia.
Since 2003, the District of Columbia Awards for Excellence in Historic Preservation has honored more than 100 outstanding preservation projects and dozens of individuals and organizations for their exceptional contributions in support of historic preservation in Washington, DC.
Nominations are due November 22nd!

Foundry Branch Trolley Trestle is the only remaining bridge along the former trolley line linking Georgetown and Glen Echo, Maryland in the District of Columbia. This line, constructed in 1896, provided the transportation to a ‘trolley’ park and thousands of Washingtonians used the line annually to access the Glen Echo Amusement Park.
The Trestle has potential to be revitalized as an historic attraction and a pedestrian and cycling path. Sign the petition to ask Mayor Bowser to #SaveTheTrestle and allow DDOT to complete its trail planning.
