No. 1 Royal Crescent is a historic house museum, owned and maintained by the Bath Preservation Trust through its membership to illustrate how wealthy owners of the late 18th century might have furnished and occupied such a house. It was purchased in 1967 by Major Bernard Cayzer, a member of the family that made its fortune through the Clan shipping line. He donated it to the Trust with an amount of money for its restoration and furnishing. The restoration was led by Philip Jebb. The Bath Preservation Trust was working during 2012–13 to re-unite Number One with its original servants' wing at Number 1A Royal Crescent, which has been in use as a separate dwelling for many years. No. 1 serves as the Trust's headquarters. Number 15 and 16 are still used as a hotel.
