H. Leyson donated the land to construct this massive brick and stone civic building. Local builders Shackleton and Whiteway won the bid for the $279,000 building, and ground-breaking took place in October of 1902. An excellent representation of early-twentieth-century civic architecture, the design features elements of the then-popular Beaux Arts style with neo-classical embellishments and an ornately appointed interior. Dedication took place in December 1904, with the U.S. post office and federal courts as the first occupants. The building later housed offices for the Department of Agriculture and the Federal Bureau of Investigation.","sponsor":null,"accessinfo":"Public","lede":"","website":"","related_resources":["<a href=\"https://npgallery.nps.gov/GetAsset/b2694698-4c33-4e3d-b1f9-d8b8740bf6dc/\" target=\"_blank\" rel=\"noreferrer noopener\">Read about the Butte National Historic Landmark District</a>","<a href=\"https://npgallery.nps.gov/GetAsset/9ecb5fd7-e392-42a7-a16e-94df0f020422\" target=\"_blank\" rel=\"noreferrer noopener\">See photos of the Butte National Historic Landmark District</a>"],"factoids":[],"files":{"https://mail.historicmt.org/files/fullsize/447ad9cc5e9e9bf6f5d2f4e247ac2f36.jpg":{"id":929,"mime-type":"image/jpeg","title":"Federal Building","description":"Federal Building, facing northeast, front view. | <a href=\"https://www.montanapictures.net/\" target=\"_blank\" rel=\"noopener\">MontanaPictures.net</a> | June 2008 | MontanaPictures.net","thumbnail":"https://mail.historicmt.org/files/square_thumbnails/447ad9cc5e9e9bf6f5d2f4e247ac2f36.jpg"},"https://mail.historicmt.org/files/fullsize/e017f51e6498a47ea52afbb237dfd1fc.jpg":{"id":1206,"mime-type":"image/jpeg","title":"Federal Building, Butte, MT","description":"Black and white stereograph image showing main facade (west elevation) of the Federal building | Montana Historical Society, N.
