The Herschel museum is located in the actual townhouse where William Herschel discovered the planet Uranus in 1781, doubling the size of the known solar system at the time, and cementing his name in history.
Set across three floors, the house has been recreated as an 18th Century townhouse as it would have been in his day, with each room is given over to a different part of his life; his musical career, his hobby of astronomy, and his everyday life with his assistant/sister. A video introduction (12 minutes, presented by the late Sir Patrick Moore) starts you off, and then the rest of the house can be seen in an hour if you're in a rush, or take it slowly and spread it out to two.
The garden (where he made his famous discovery) has been restored to its period state, and is beautiful. The staff member on duty was pleasant, informative and enthusiastic, a real ambassador for the property.
