The ruined Grade II-listed Roundhouse at Brogborough, which dates from the first half of the 17th Century, has been hiding a unique and largely forgotten, site.

It is the location of a medieval 12th Century Motte & Bailey castle and ringwork, one of only 60 in the UK.

Large earthworks are still in place making this site of interest to both local residents and organisations, such as Historic England, but campaigners say the location is under threat.

Save Brogborough Ringwork, a local campaign group, said the castle site’s setting with its “amazing” 360-degree views over the surrounding countryside is what makes the location so special.

Adding that these views will be impeded by the proposed increase in warehousing at Marston Gate under Central Bedfordshire’s Local Plan.

Save Brogborough Ringwork says the modifications for proposed MM33 Marston Gate Expansion do not go far enough, as it still involves warehousing at 18.5m high, running alongside the A507.

The group said this will impact local Greensand Ridge walks, the Grade II* listed Segenhoe Manor, as well as overwhelming the ancient ringworks site.

The campaigners are calling on residents to contact Central Bedfordshire Council to object to the plans. The deadline is noon on 5 May 2021.
