A RELIC of the Cold War is to be opened to visitors.

Work will start next month on a bomb-proof bunker behind Shelley House in Acomb Road, York.

When the project is complete owners English Heritage plans to open it for 20 days a year for groups on educational visits.

The bunker, which was intended to house up to 40 people, was built in 1961 to withstand a nuclear explosion and act as a centre for monitoring conditions after an attack.

Observers in bunkers around the county would have reported to the Acomb shelter if war had broken out.

The bunker passed to English Heritage when the Cold War came to an end and is now a scheduled monument.
