Mrs Kiwi is from RAF Long Sutton and has asked me to pass on her thanks theladf, for the pictures of the Basingstoke Canal and castle. She said the castle has been cleared as it used to be quite overgrown.
English heritage/the National Trust & hampshire council spent some money on renovation and repair last year. Better access from canal towpath, more information about the castles history and they did some work on the castle to make loose masonry safe.
