Loveland Block and Coors Building, commercieel gebouw in Colorado, Verenigde Staten van Amerika

The Loveland Block is a two-story brick commercial building in downtown Golden, Colorado, with a flat-roofed front section built in 1863 and a gabled rear portion added in 1865–66. Its 1868 mansard third story was largely unused, and in 1905 a plate-glass storefront with an ornamental corner column replaced the original arched entrance. The adjacent Coors Building is part of the same National Register listing.

The Loveland Block's front section was built in 1863 by William A.H. Loveland and Golden City Lodge #1, the first Masonic lodge in Colorado, with contractor Duncan E. Harrison. Loveland extended it in 1866 to house the territorial legislature: the House met in the Masonic Hall, the Council at the west end of the upper floor, and the Territorial Library below under Edward L. Berthoud. The legislature met here from 1866 to 1867, then moved to Denver after a Council vote decided by one margin, alleged to have been bought.

The building is named for William A.H. Loveland, who built it in 1863 with Golden City Lodge #1, the first Masonic lodge in Colorado. The lodge met on the second floor, while Loveland ran his mercantile below. The store he had started across Washington Avenue in 1859 closed in 1978 after 119 years, 57 of them under the family of German immigrant Nicholas Koenig.

The buildings sit on Washington Avenue in downtown Golden and are easily accessible on foot as part of the historic district alongside other attractions. The Loveland Block now operates as a restaurant and bar where visitors can step inside and experience the space, while the Coors Building also contains shops and dining options.

The Mercantile began across Washington Avenue in 1859 and moved into the Loveland Block, closing in 1978 after 119 years; one family, headed by German immigrant Nicholas Koenig, ran it for 57 of those years. In 1905 Koenig hired contractor Perre O. Unger to cut a plate-glass storefront into the arched entrance and installed the building's 2-ton Diebold safe.
