The history of this stunningly beautiful house is quite a story in itself. But now that it also includes the Hampstead Museum, the history becomes truly incredible. The ground floor is home to their permanent exhibition which goes back before the Doomsday, through every age to the present day. And their art collection, mostly donated by famous residents, is something they are rightfully very proud of.
