Library of Congress

Project Location:
Summary:
We are restoring the verdigris patina from the bronze to bring it back to its original satin finish.

The Durable Restoration Company, Mid-Atlantic, is restoring the bronze flagpoles and lanterns outside of the John Adams Building, Washington, District of Columbia.


The John Adams Building is the second oldest of the four buildings of the Library of Congress of the United States. It is named for John Adams, the second president, who signed the law creating the Library of Congress. The building is in the Capitol Hill district of Washington D.C. next to the Library's main building (the Thomas Jefferson Building).


Our full scope of work is the restoration of 14 exterior bronze lanterns and 2 bronze flagpoles. Our sub-contractor, Acu-Bright, out of New Hampshire, is restoring them back to their new bronze finish using very low (15) PSI micro abrasion. They are then lacquered in order to ensure they don’t patina. The building has an Art Deco Style which is seen in the lantern details.
