Tate Britain

The Tate Modern, London is a museum of English paintings with sixteenth century works by artists such as Turner, Constable and Blake. It is very reminiscent of the National Gallery with its majestic halls. They also have temporary exhibitions (with an admission fee). To get there take the Victoria line (blue) to Pimlico station, nearby is a jetty with a boat that goes directly to the Tate Modern, the Tate Boat. I really enjoyed visiting it, it's a beautiful museum, the building is nice and has a design school.

I've spent almost four hours inside. Seeing early modern paintings was so helpful to observe artists style.
