The Herschel Museum of Astronomy at 19 New King Street, Bath, England, is a museum that was inaugurated in 1981. It is located in a town house that was formerly the home of William Herschel and his sister Caroline. Location The museum is situated in the former home of the Herschels at 19 New King Street (south side) in Bath, England. The building is a particularly well-preserved small town house of the period. The modest town-house covers five floors, and includes two reception rooms on the ground and first floor. The town house is part of a terrace that was built around 1764-1770. The building is constructed from Bath stone ashlar, with some coursed rubble at the rear, and slate Mansard roofs with pantiling on the internal slopes. The entrance is on the left-hand side of the building, which has three storeys, as well as an attic and basement, each of which have two sash windows. The building represents a middle-grade Georgian town house, typical of the homes of artisans and tradesmen of the city of Bath (but contrasting with Bath's grand visitor houses) The Herschels moved into 19 New King Street in 1777, at which point the builders would have still been present, and the road would have been unmetalled. William discovered Uranus whilst residing in the house in March 1781 using a 7 foot telescope designed and built in the attached workshop. William left Bath in 1782, but Caroline, along with their brother Alexander, remained at the house until 1784. The building has been designated by English Heritage as a grade II* listed building. The building was restored in 1981, and again in 2000, using period detailed wallpaper based on fragments discovered in other Bath houses, and carpets based on 18th century designs. Museum In 1977 the William Herschel Society was set up to gather support for the rescue of the building. It was purchased in 1981 with the aid of Doctors Leslie and Elizabeth Hilliard, saving it from demolition. The main-belt asteroid 6395 Hilliard was later named in their honor. The house was subsequently transferred as a donation to the Herschel House Trust. The museum was opened on 13 March 1981, exactly 200 years after Herschel discovered Uranus. The museum is governed by the Herschel House Trust, a registered charity. The Bath Preservation Trust became the sole trustee of the Herschel House Trust in July 2015. The
