It's at an RSPB Reserve on the Suffolk coast called Minsmere. Really nice place to visit and go for a walk. Coincidentally as I was walking round, the Grace Spitfire which is based at nearby Bent Waters decided to fly over and was thown around a bit over the coast. Normally it's me that goes to see the aircraft not the other way round.
Sounds like a lovely place. I thought the Grace Spitfire was based at Duxford? I don't know if anything is based at Bentwaters but I'm not overly familiar with everything in and out of there really, so I'm open to being wrong.
