Middlesex, with the east in the former Liberty of Glasshouse Yard, with the former Liberty of Charterhouse just to the north. These three units were, with nearby Clerkenwell, part of the former Finsbury Division. They later became part of the Metropolitan Borough of Finsbury, formed in 1900. In 1965 the Metropolitan Boroughs of Finsbury and Islington merged to form the new London Borough of Islington. Plague burials In 2014 evidence of the large burial pit for plague victims dating from 1348 to 1350, the time of the Black death, was discovered under the square by workers building the Crossrail project.

It comprises student accommodation and departments of Barts and The London School of Medicine and Dentistry: Barts Cancer Institute (BCI), the Wolfson Institute of Preventive Medicine and the William Harvey Research Institute (WHRI). The BCI and the Centre for Cancer Prevention (CCP) within the Wolfson Institute also make up the Cancer Research UK Barts Centre of Excellence, together with Barts and the London NHS Trust.
