 In 2006 it was listed on the National Register of Historic Places; five years later it was designated a town landmark as well.While it is a fine example of its school of architecture, the house's primary historical value is that it was the home of suffragist Carrie Chapman Catt and her partner Mary Hay from 1919 to 1928.That period was the height of her activism; it began with the passage and ratification of the Nineteenth Amendment, which granted women the right to vote, and continued with her founding of the League of Women Voters and advocacy of women's suffrage in other countries.
