Dulwich Picture Gallery

A beautiful building and collection located in a suburb of London which is well worth the effort. It isn't on any tube line, so you have to go to Victoria station or London Bridge station to catch a train there, which only takes about 15 minutes. Once there, it feels like you are in the countryside, and are glad that there is no Tube access. The gallery itself is also intimate and has many high quality paintings from Dutch masters and Italian old masters. The one which you probably will remember will be Rembrandt's Girl at a Window.
