Faneuil Hall was opened in 1743 (and was the site of several speeches by luminaries such as Samuel Adams.) and was present when Rees and Lydia visited Boston in 1801.
Built by slave merchant Peter Faneuil as a gift to the town, it was funded in part by the profits from slave trading. The building was begun in 1740 with an open ground floor serving as a market house with rooms on the second floor. The National Park Service believes early slave auctions took place nearby.
The hall has been rebuilt several times. It was destroyed in 1761 by fire and was greatly expanded in 1806 by Charles Bulfinch. In 1960, Faneuil Hall was put on the National Register of Historic Places. It is still in use and can be visited.
