The home of Roosevelt's friend Ansley Wilcox, this mansion became famous on September 14, 1901, when Teddy was sworn in as the 26th president of the United States in the library.

The room has been re-created to reflect what it looked like on the inaugural day, and the rest of the home is an interesting glimpse into how Buffalo's wealthiest families lived at the turn of the 20th century. In 2009, a major renovation introduced new exhibits and re-created the original carriage house, which is now home to the visitors center and a shop for all things TR.
