The oldest structure on the National Mall in Washington, DC was relocated in advance of a renovation project that will transform it into a new education center. The Lockkeeper’s House, built in 1833 during the extension of the Chesapeake and Ohio Canal, was moved fifty feet back from its former location on busy Constitution Avenue. The move is part of an ongoing restoration project at the National Mall that also includes biofilm removal from the Jefferson Monument’s dome. The transition includes construction of a new garden and plaza for the house; it is expected to be completed in 2018. You can read about the delicate work of moving the fragile 184-year-old structure in this press release by the National Park Service and see the future plans for the house on the Trust for the National Mall’s website.
