Chatsworth visit

We've lived here just the Cheshire side of the boundary with Derbyshire 12 years and never been to see Chatsworth House, the home of the late Duke of Devonshire, just 20 miles away. Isn't it often the way, you live somewhere, you don't get to see the sights. We're going to be moving back to our roots in Dorset this year, so we'd better catch up!
So here's an internal window, a lovely patchwork of sheets of blue john, a famous Peak District mineral; a quarter of a precision display of seashells; a marble tabletop.
