Work is being done to preserve a historic Sudbury moat after it was included on the Historic England ‘at risk’ list.
Wood Hall moat, earthworks at the site of a former timber-framed house, is owned by Babergh District Council.
The council-owned site as a whole encompasses both the monument and some additional land and is partly being managed by regular grass cutting, with part of it being developed into mature woodland.
A Babergh spokesman said that part of the threat may be perceived to be coming from the possibility of the maturing woodland impacting on the earthworks there, with roots breaking up the ground or a falling trees doing damage,
The council has yet to receive details from Historic England explaining the decision.
“There is regular maintenance of the open space to stop trees or larger plants taking root there and of course no development or building is taking place at the monument,” added the spokesman. “The site has been on the register since 2014 and we’re pleased to see the listing describes the trend as ‘improving’.”
