Archive office opens after revamp

The 7 July books of condolence are in the records office

London's archives, which house a copy of the 1297 Magna Carta and the 7 July books of condolence, have reopened after undergoing a £2m revamp.

The London Metropolitan Archives in Clerkenwell, City of London, closed three months ago for the upgrade.

The archives chart London's history since the 11th Century and house an extensive collection of maps, prints and photographs of the city.

The rarest documents are stored in high-security safety vaults.

Letters from Florence Nightingale and Foundling Hospital's records of abandoned children are also housed in the collection.

Along with modernising its stock and display facilities the archives now include 48 digital workstations for visitors who want to trace their family's history or London's past.
