448th Bombardment Group at Seething
The former control tower has been renovated and has become a memorial museum to the 448th Bomb Group.
It contains the group roll of honour, wartime diaries and photographs, plus various artefacts and memorabilia, with additional displays in a Nissen building.
It's open to the public on the first Sunday of the month from May to October, but can be inspected at other times by special request.
