Upper Main Street Historic District (Lafayette, Indiana)
Upper Main Street Historic District is a national historic district located at Lafayette, Tippecanoe County, Indiana. Sixth Street was the City of Lafayette's eastern boundary when it was originally platted. By 1840, the boundary was extended to include Lake Erie and Wabash Railroad at Eleventh Street. This area became the cities commercial center. Businesses around Eleventh Street developed to meet the traveling publics needs. The Enterprise Hotel, at 1015 Main Street, as well as the Alt Heidelberg, American Lafayette and the Derby Hotel were early established by 1899. All structures are historically  ‘Notable’ or ‘Outstanding’ examples within the Historic District. An ‘O’ rating signifies that the structure had enough historic or architectural significance to be considered for individual listing in the National Register of Historic Places. The ‘N’ rating signifies that the structure is above average and may, with further investigation be eligible for an individual listing. The contributing structures meet the basic inventory qualifications, but fails to meet individual merit, but in combination with other closely placed similar structures warrants inclusion in an historic district.
