Secrets of Clerkenwell

Stroll through Clerkenwell on a two-hour walk that takes in the remains of the four great religious houses (St Bartholomew's in Smithfield, Charterhouse, St John's Priory and St Mary's Nunnery), while listening to guide Rob Smith talk about the area's burial grounds, brothels and taverns. The walk begins at Barbican tube, and ends on Clerkenwell Green – perfect for lunching at Lenin's local.
