One of Bath's gems, this elegant 18th-century building and its modern extension house a superb collection of 17th- and 18th-century decorative arts, ceramics, and silverware. Highlights include paintings by Gainsborough (The Byam Family, on indefinite loan) and George Stubbs (Reverend Carter Thelwall and Family), and a hilarious collection of caricatures of the Georgian city's fashionable elite. In its original incarnation as the Sydney Hotel, the house was one of the pivots of Bath's high society, which came to perambulate in the pleasure gardens (Sydney Gardens) that still lie behind it. One visitor was Jane Austen, whose main Bath residence was No. 4 Sydney Place, a brief stroll from the museum. There's an excellent café and tea garden on-site.
