United States copyright law does not protect architectural works before 1990年12月1日. 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 1990年12月1日, is in the public domain in the United States. For images of architectural works in the United States completed on or after 1990年12月1日, please use {{FoP-US}} on the description pages of the images.
