The Architectural Ambler is an electronic publication of the Trust for Architectural Easements.
"The Ambler explores the history and architecture of historic districts listed in the National Register of Historic Places, the nation’s official list of certified historic districts and buildings. Any building, structure, or land area which is listed in the National Register of Historic Places, or any building which is located in a registered historic district and is certified by the United States Secretary of the Interior as being of historic significance to its historic district, may be protected by a historic preservation easement, and the Trust is one of the largest preservation easement-holding organizations in the nation. There are hundreds of historic districts listed in the National Register, and each one tells a unique story from the history of the United States. The Ambler will bring these stories to you."
