The British public are so damned polite and relentless in their praise that it comes as a breath of fresh air when you receive a complaint. About five, or it may have been ten, years ago (probably ten as it came hand-written) I received a letter from a visitor saying that it was all very well building gazebos and towers from which to enjoy the view, but this was next to useless if the viewer wasn’t given any clue as to what they were looking at. A good point, I thought, and I wrote back promising to provide some guidance. I’m about to fulfil that promise with an explanatory map carved in stone by Alan Ward. This video shows Alan working away at the top of the tower, his chisel producing a gentle, hypnotic rhythm – an indication of how he earned the affectionate nickname of “Mr Chips”.
