Areas of Long Curtain Moat will benefit from maintenance work throughout September and October as part of early enabling works for the Southsea Coastal Scheme.
The work, which will take place on weekdays between 7am-7pm, will improve the condition of the heritage assets prior to work potentially beginning on new sea defences in 2020.
From Monday 9th September, repointing work has started to both the moat wall and landside walls. This will involve limited heavy machinery due to the nature of the work with most being carried out using hand tools to ensure the necessary protection of the heritage areas. Seafront users may notice contractors working on pontoons in the moat during the duration of this work.
There may be some pedestrian diversions in place as a result of the work and these will be clearly signposted whilst in effect.
Work will also take place on Nelson's Tunnel which will be closed for the duration of the work with a suitable diversion in place.
Councillor Dave Ashmore, cabinet member for environment and climate change at Portsmouth City Council, is pleased to see this work taking place.
"Long Curtain Moat and the surrounding areas are so important to Portsmouth and very highly regarded nationally in terms of their historic importance as a Scheduled Ancient Monument. We are pleased to be able to do our part in ensuring they remain in good condition and can continue to be enjoyed by future generations."
The work is scheduled to be complete by the end of October 2019.
