The original Commercial Historic District of the City of Albert Lea consisted of three square blocks of forty-eight structures built between 1874 and 1928. Featuring iconic examples of American architecture in a variety of styles, including Beaux Arts, Classic Revival, Neoclassical, Art Nouveau, and Craftsman, the district was listed on the National Register of Historic Places in 1987. Sixty-four additional properties added in 2004 extended its period of significance to 1953.
