Leighton House Museum
This house is a unique setting to see works displayed by Leighton himself as well as others, such as the Pre-Raphaelites, Millais & Burne-Jones.
You can find more details on the web by searching for "Leighton House" at
The Royal Borough of Kensington & Chelsea website.
When you have finished touring the house, do visit the nearby Holland Park - one of London's finest small parks. I have got to admit to a soft spot for Holland Park: in my student days, I often used to laze on its lawns.
