The Ansonia and Calumet Buildings are two of the most important examples of Art Nouveau
architecture remaining in the United States. In addition to their unique architectural expression,
these buildings have played roles in Buffalo's revitalization. The Ansonia and an adjacent building
were gutted and converted into apartments during the 1980s, one of the first such downtown
conversions. The renovation of the Calumet as a restaurant and jazz venue sparked the
renaissance of Chippewa Street in the 1990s.
