The Federal-style house was completed in 1816 by Gideon Granger, postmaster general for presidents Thomas Jefferson and James Madison. It contains what's known as a flying staircase, and its nine rooms have hand-carved woodwork and many of the original furnishings and paintings. Free guided daily tours are available. The carriage house displays 93 horse-drawn vehicles, including an undertaker's hearse. The many annual events include a Civil War encampment in September
and a Festival of Trees in November and December. The museum runs 45-minute narrated carriage tours of Canandaigua on Friday and Sunday, June through September. The trips cost $20, and reservations are required. Weather permitting, sleigh rides are offered on Sunday at 1 pm, January–March.
