Wiltshire 22

Paul Martin presents from Longleat in Wiltshire, home to the 7th Marquess of Bath, and there is a wide variety of antiques and collectibles put before experts Claire Rawle and Michael Baggott at the valuation tables, including a stunning amethyst and pearl brooch. But it's an autograph album with a set of Beatles signatures that has the experts guessing. Are they genuine or not? All is revealed at the auction.

Paul also takes a trip to London to unearth the hidden architectural gems of one of Wiltshire's most famous sons, Sir Christopher Wren, and he pulls on his wetsuit and dives into the River Frome to discover the joys of wild swimming with one of the oldest river-swimming clubs in the country.
