Visit Islington Museum's latest exhibition: Undercurrent - Islington's Lost Waterways. Open now until August 19th 2025.

Join Islington Museum and Clerkenwell &amp; Islington Guides for a fascinating walk from Moorgate to Old Street, uncovering the secrets of the lost River Walbrook and the watery history still shaping the city today.Though one of London’s smallest lost rivers, the Walbrook once meandered through Finsbury and St Luke’s before flowing into the Thames. Dammed by the Roman city wall, it flooded the area to form the marshy Moorfields. Today, it runs silently beneath our feet - diverted into sewers - but its presence still leaves ripples across the modern landscape.Along the way, you’ll hear stories of medieval wells, a Georgian swimming pool, Victorian innovations in sanitation, a church slowly sinking into soggy ground and more. It’s a journey through time, tracing how water shaped the lives, buildings, and streets of this corner of London.
