One of London’s first suburbs, this quiet yet central area is home to arts and crafts workshops and the centre of the diamond trade in the UK. But Clerkenwell’s past is rooted in Marxism, protests and prisons. The Italian community has a strong foundation in Clerkenwell. Fagin’s den in Oliver Twist, Ely Palace, Spa’s and nunneries all have a part to play in this fascinating tour of this quiet quarter. London Undone knows it well.
