The Art Fund said the money had been raised after what was the largest ever arts crowdfunding campaign.
A £3.5m fundraising campaign to save for the nation the idyllic home of artist, activist and film maker Derek Jarman has been successful, it has been announced.
Maria Balshaw, the director of Tate, said: “The success of the campaign to save Prospect Cottage raises our spirits in these difficult times.
Jarman’s archive from the cottage – notebooks, sketchbooks, letters, drawings and photographs – will be looked after by Tate Britain.
