Circuit: A National Youth Network for the Visual Arts aims to reach 80,000 people aged between 15 and 25, who have the least access to the arts, over four years.
The money is the latest in a series of awards being made by the foundation to mark its 25th anniversary. A £5m donation was made to the Roundhouse Studios in Camden, London, in October.
Circuit is being launched in April with a young people’s festival in the Tanks at Tate Modern in London. It is being rolled out across the UK through selected galleries in the Plus Tate network, which supports the development of visual arts.
These include firstsite in Colchester, Essex, Mostyn in Llandudno, north Wales, the Nottingham Contemporary gallery, Whitworth Art Gallery in Manchester, and Wysing Arts Centre and Kettle’s Yard in Cambridge.
All four Tate galleries will also be involved: Tate Modern and Tate Britain in London, Tate Liverpool, and Tate St Ives in Cornwall.
Jane Hamlyn, chair of the foundation set up by her father, said: "We are delighted to be supporting Circuit, as a national youth initiative, working through a group of fantastic organisations including Tate, with high ambitions for reaching and opening up the arts to so many young people in the UK."
