Who was Mary Seacole?
A statue honouring the Jamaican-born nurse Mary Seacole has been unveiled in London.
Mary was born in the capital of Jamaica, Kingston, in 1805 and was the daughter of a Jamaican mother and a Scottish father who was a soldier.
Her mother ran a hotel and Mary often helped her to treat sick and injured soldiers who came there.
In 1853 the Crimean War broke out - Mary went there to help.
She built a little hut out of old metal sheets and there she treated and fed many soldiers who were hurt fighting in the war.
