Take a stroll down the coast from the Eng­lish sea­side town of Mar­gate and you’ll come to Wal­pole Bay, where a vast tidal pool stretch­es out beneath the chalk cliffs of Kent. Con­struct­ed in 1937, it’s as pop­u­lar a bathing spot as ever – even when the Eng­lish weath­er isn’t play­ing ball – and the ulti­mate place to catch the fiery Mar­gate sun­sets immor­talised in paint by JMW Turn­er.
