In this illustrated talk, Rachel Lichtenstein reveals some of the extraordinary stories she uncovered whilst researching her latest book Diamond Street - The Hidden World of Hatton Garden.

Best known as London's diamond and jewellery quarter, this historic area of the city is also a place of underground vaults, subterranean rivers, monastic dynasties and lost landscapes.

Intimately connected to the place, both through her family's jewellery business and as an artist-archivist of London streets, Lichtenstein shares the rich and surprising history of Hatton Garden, that secret 'fold in the map'.
