On Friday 17 April 2015, photographer Quintin Lake set off from the steps of St Paul's Cathedral on a five-year journey that would take him around the entire coastline of mainland Britain. Armed with twenty kilos of hiking and photography gear, he walked 11,000 kilometres in 454 days with one goal in mind: to produce a body of photographic work that gets under the surface of the island nation that we call home. Carefully curated with over 1,300 photos and interspersed with stories of Quintin's adventures, this book is an immersive visual experience that showcases Britain as you've never seen it before. Discover charming seaside towns such as Staithes in Yorkshire, venture to the desert landscape of Dungeness in Kent and marvel at the beautiful desolation of Scotland's Knoydart Peninsula. Explore the contrast between industry and nature along the Welsh coast path, where plumes of steam rising from the Port Talbot steelworks are as jaw-dropping as the stunning Worm's Head on the Gower Peninsula. And follow Quintin as he narrates the monumental challenges of wild camping - from battling with midges and stress fractures, to clambering up cliffs to escape a rising tide. Filled with striking photos that capture the glorious and often surprising world between land and sea, The Perimeter is a celebration of Britain - a small island with a vast coastline.
