The National Museum of Liverpool has one of the most important collections of Pre-Raphaelite art in the world over its three galleries. The Pre-Raphaelites were a group of artists led by Dante Gabriel Rossetti, William Holman Hunt and John Everett Millais who started the movement in 1848. They are known for vivid colors and depictions of 19th century social life.
If this has sparked your interest in the Pre-Raphaelite movement, Andrew Lloyd Weber made a 4 part documentary which is available on YouTube. Here is the first episode.
