They might be cute and fury but the resident rabbit population is causing problems at the National Trust owned Tattershall Castle.
In fact, rabbits could be responsible for an important item of the castle’s history literally disappearing down the pan.
Staff are battling to save the castle’s 100-year-old earth closet, a Grade One listed “amenity” which is essentially a loo without water.
The closet was installed during a major renovation by Lord Curzon in the early 1900s.
To the uninitiated, it resembles a hole in the ground, but is in danger of collapsing into the moat because rabbits - and other animals - have burrowed too close to it.
Paul Robinson, Visitor Experience Manager at the castle, said: “The closet is an important part of our history.
“No doubt, a lot of very important people have used it. It must be one of the oldest toilets in the area. It is Grade One listed and we don’t want to lose it.”
A structural survey has suggested the closet needs to be ‘propped up’ - to stop it falling into the moat.
The National Trust is not flushed with cash but has stumped up the money for the first part of the repair work. Staff hope more funding could be in the pipeline.
On a more serious note, the closest is close to a section of the castle’s original 15th century wall which is also in danger of collapsing.
Mr Robinson explained: “There’s a huge crack in the wall and we’re looking to repair that as soon as possible.”
*It is thought the first castle was built by Robert de Tattershall in 1231.
The current brick structure - featuring the 130 foot high Great Tower - was built by Ralph, 3rd Lord Cromwell, Treasurer of England, between 1430 and 1450.
