The Wallace Collection, located in a stunning 18th century townhouse in Marylebone, is home to an impressive 5,500 items from the 15th to the 19th centuries which can be viewed for free, however it is far less known than other museums like the Tate and National Gallery.
The collection was amassed between the 18th and 19th centuries by the Marquesses of Hertford and Sir Richard Wallace, and made available to the public by Lady Wallace in 1897, who wanted it to be kept together. It covers many eras, from the Renaissance works of Titian and Rembrandt through to latter additions of modern art by David Hockney and Lucian Freud.
As well as paintings, displays include Baroque furniture, medieval armor, ceramics and decorative arts. Regular exhibitions take place throughout the year alongside the permanent collection, and for £30 a year you can become a member to see these for free too.
