Explore Secret Stories Herne Hill\'s Think & Stink Tour, a self-guided interactive walking tour to enjoy whenever you want. This audio tour is part of an Ordnance Survey series of bite-sized, tongue-in-cheek stories. Expect nutty nature, smelly smugglers, raucous royals you get the idea. Turn back time as we explore the centuries of history that can still be found in the streets around Herne Hill. Walk in the footsteps of a Victorian radical thinker and nature enthusiast who was ahead of his time and discover how he inadvertently inspired Mahatma Gandhi. Find out why we have an American billionaire to thank for a quirky public library and how it changed the game for libraries everywhere. If you think the Thames is dirty now, wait until you find out what a stink pipe is and how, without it, London would be a much smellier place today. Meet the religious power couple, William and Catherine Booth, who carved their own charitable path through London’s poorer districts.
