My wife and I spent ours at Bawdsey Manor (nee Raf Bawdsey) the home of the birthplace of RADAR. We had a wonderful 3 course lunch in the Manor in the company of the members of the Bawdsey Reunion Assosiation and visited the on site RADAR museum, housed in the old transmitter block in which the original Chain Home Low RADAR was developed.
The current owners of the Manor gave us a guided tour of the magnificent building, now an International school, and it's equally impressive gardens.
The lunch is an annual event that I would recommend to anyone who has a link with this historic site.
