Explore Secret Stories RGS Out of Sight: Folkestone Tour, a self-guided interactive walking tour to enjoy whenever you want. A short walk tracing Folkestone\'s lost river. This tour forms part of the Discovering Britain series created by the Royal Geographical Society (with IBG) to delve deeper into Britain\'s landscapes. Water is a source of nourishment and power. We need it to grow our food, wash our clothes and take away our waste. People settle near rivers and water sources, and Folkestone wouldn’t be here without it. The Pent stream, an ancient watercourse flowing from the North Downs to the sea, was once vital to the town. Today its presence is barely noticed. Now hidden and built over by urbanisation, it’s deemed a threat not a life force. This trail maps the route of this lost river in the lie of the land, street names and buildings.  It was inspired by Pent Houses, a public artwork by Diane Dever and Jonathan Wright, originally exhibited as part of the Folkestone Trienniale 2014.  Total length: 1.5 miles; Suggested age range: 7+ Purchase this Tour (and more) in the Secret Stories App, available for free download from Android Play and Apple App store.
