The proposed £19m history centre to be built to the north of Brighton has been approved by Brighton and Hove City council‘s planners.
It is hoped The Keep will be completed in time for opening in 2013 with work now expected to begin at Woollards Field, near Falmer, next summer.
The project is a collaboration between East Sussex County Council, Brighton & Hove City Council and the University of Sussex.
Councillor Bob Tidy, community services member at East Sussex County Council, said: “The Keep will be the new home for over 900 years of historical resources and collections of local, national and international importance.
“It will house over six miles of archives including written records, maps, plans, films, photographs, prints and drawings. Councils up and down the country are looking at all their planned new schemes and only putting forward those they believe are their key priorities and for which funding has already been planned.
“The Keep falls into that category and I’m delighted that it has been given the go-ahead.”
