The transformation of the historic Wisbech Castle has led to the discovery of a secret room.

The walled-up underground room is empty, sits within the grounds of the site and is not on any current maps.

It was found by team members of The Wisbech Castle Project on their restoration quest last week – but they are keeping tight-lipped about the find – with more news set to follow in September.

They said: “This room is not on the current maps and although we did wonder if there might be something there we had not confirmed there was ... until now.

“Two test drill holes have revealed a complete underground room, in good condition, which has been hidden away for a very long time indeed. It appears to be empty, but clear and mostly dry.

“Now we will need to do some checks to see if it’s safe to open the room up and once that it confirmed we’d like to do so.”

The castle was transferred to Wisbech Town Council on a long lease with a peppercorn rent along with a £150,000 loan from the county council earlier this year.

Repayable over 25 years, the money was awarded so that repairs and improvements could be carried out.
