Theodore Roosevelt Inaugural National Historic Site preserves the Ansley Wilcox House, at 641 Delaware Avenue in Buffalo, New York.

The structure that would later be incorporated into the Theodore Roosevelt Inaugural National Historic Site started life in 1840 as the Barracks' officers' quarters.

Approximately 50 dignitaries, family members and cabinet officials gathered in the front library for the inauguration, while Federal Judge John R. Hazel administered the oath.

The proprietors removed interior walls, demolished a carriage house, and painted many of the finished wood surfaces before the restaurant ceased operations in 1961.

[2] The first part of the house is a museum displaying many items from the 1901 Pan-American Exposition, including wine glasses, plates, playing cards, and the key to the Temple of Music.
