The sparse House of Representatives on the first floor (Lower House)—where the desks for 106 representatives from 16 states still sit—looks much as it did when it hosted John Adams’ inauguration in 1797. The second floor (Upper House), where the U.S. Senate met, is more elaborate, with deep green walls and fabric, a hand-loomed carpet bearing seals of the original 13 states, and oil portraits of Louis XVI and Marie Antoinette bequeathed by the French.
Entry to Congress Hall is free and open to the public on a first-come, first-served basis. From March through December, visitors can only explore the building on a 20-minute guided tour. Although organized tours are not offered in January and February, park rangers are on hand to answer questions. Congress Hall is also a typical stop on history-themed walking tours of Philadelphia, which is a good way to get a broader picture of the city’s history.
