The National Register of Historic Places Third Avenue/Downtown Historic District is of historical significance because it is associated with the developing and maturing of the city of Sturgeon Bay as the traditional focus of commercial activity within the community and the region. It is of architectural significance because it is the most intact and representational grouping of late 19th and early 20th Century commercial and civic buildings in Sturgeon Bay. It is not characterized by any dominant architectural style but reflects a wide variety of traditional commercial building modes common throughout Wisconsin and the Midwest during the decades that bracket the turn of the century. Few of these buildings have been substantially eroded, and many examples both of anonymous craftsmanship and the use of distinctive local limestone remain.
This is Part 1 of a two-part tour of the District.
