Plans to build a £19m archive centre in East Sussex have been submitted to a local authority.
East Sussex County Council said The Keep would house more than 900 years of Sussex history at Woollards Field near Falmer.
The council said the centre remained a key priority despite restrictions on spending following the government's Spending Review.
Brighton and Hove City Council will discuss the proposal on 14 January.
If the plans are approved, work is expected to begin next summer, with the centre opening to the public in 2013.
The current archive and record office at The Maltings in Lewes has been in operation since 1949.
In 2006, the National Archives inspectors said work on a new record office should be started within five years.
The project is a partnership between the county council, Brighton and Hove City Council and the University of Sussex.
