United States copyright law does not protect architectural works before 1 December 1990. In 1990, the Architectural Works Copyright Protection Act amended subsection 102(a) of the US copyright law by adding paragraph (8), "architectural works." A building that was substantially constructed or for which the plans were otherwise published before 1 December 1990, is in the public domain in the United States. For images of architectural works in the United States completed on or after 1 December 1990, please use {{FoP-US}} on the description pages of the images.
