In June last year, monitoring of the shelters, showed that they needed to be closed in high winds.
Monitoring of the condition of the shelters has continued, and the latest report received states that the condition of the concrete of the shelters has deteriorated to such an extent that the shelters should now be taken permanently out of use, and barriers should be erected to limit access to the shelters to qualified personnel only.
The butterfly shelters were built in the 1960s and have long divided opinion in the resort as to how they fit in to the Edwardian splendour of ‘Sunny Hunny’.
Elizabeth Nockolds, cabinet member for culture, heritage and health, said: “It’s a shame that we are having to do this at this time of year, but ultimately we have to take our duty of care seriously.
“We have been advised to barrier off the shelters because they are unsafe, and that is what we have done.
“The shelters are quite iconic in Hunstanton and have always been fairly well used.
“However, they have deteriorated over the years, as is the case with this sort of concrete, and now we have no choice but to cordon off the area with a view to eventually taking down the shelters and potentially replacing them.”
The borough council has applied to the Heritage Lottery Fund for a grant to remove and replace the shelters. The Stage 1 application, for funding to develop plans, has been successful.
The Stage 2 application has been submitted, and the borough council is hopeful that the outcome will be known by the end of June.
If the application is successful, work on the shelters will take place over the winter, and they would reopen in late spring.
