The Wallace Collection is a national museum which displays the wonderful works of art collected in the eighteenth and nineteenth centuries by the first four Marquesses of Hertford and Sir Richard Wallace, the son of the 4th Marquess. It was bequeathed to the British nation by Sir Richard’s widow, Lady Wallace, in 1897.
It is probably best known for its paintings by artists such as Titian, Rembrandt, Hals (The Laughing Cavalier) and Velázquez and for its superb collections of eighteenth-century French paintings, porcelain, furniture and gold boxes, probably the best to be found anywhere outside France.

The British Museum is a museum of human history and culture in London. Its collections, which number more than seven million objects, are amongst the largest and most comprehensive in the world and originate from all continents, illustrating and documenting the story of human culture from its beginnings to the present. The British Museum was established in 1753, largely based on the collections of the physician and scientist Sir Hans Sloane. Objects in the collection include the Elgin Marbles from the Parthenon.
The collections in Tate Modern consist of works of international modern and contemporary art dating from 1900 until today. The Tate collection is on display on levels three and five of the building, while level four houses large temporary exhibitions and a small exhibition space on level two houses work by contemporary artists.
