The Crystal Grotto
Painshill Park, Cobham, Surrey
Charles Hamilton created Painshill as a romantic landscape garden in the 1700s. Its grotto, on an island in the lake, was lined with thousands of pieces of crystal, quartz and gypsum, which sparkled in the light reflected off the water.

The Ledger of Lost Britain
The Romans arrived in AD 43. For most people that is where the history of Britain begins. But by the time the legions landed, people had already been living on these islands for thousands of years. They had hunted, farmed, mined flint, dragged stones across the country, raised a hill by hand, and buried their dead in great tombs. They left no written words. What they left was the ground itself. Every place in this book can be visited, or has been dug up, or is in a museum.
