A £3.6 million painting has been exhibited in a women's prison as part of a nationwide tour.

A rare self portrait by the celebrated artist of Italian Baroque, Artemisia Gentileschi, went on display at HMP Send, a female prison in Surrey, from Monday 20 May to Wednesday 22 May.

The 17th-century painting, titled Self Portrait as Saint Catherine of Alexandria, was recently acquired by the National Gallery and is the first painting from a national collection to go on display in a prison.

HMP Send is the painting’s latest venue in a nationwide tour that has seen it visit a Yorkshire GP surgery, a Newcastle high school and Glasgow Women’s Library.

In December last year, the National Gallery announced that the painting would be taken to "unusual and unexpected venues" around the country as a "Christmas present for the nation".
