Tavistock Square is a public square in Bloomsbury, in the London Borough of Camden.
Tavistock Square was built shortly after 1806 by the property developer James Burton and the master builder Thomas Cubitt for Francis Russell, 5th Duke of Bedford, and formed part of the Bedford Estate in London, owned by the Dukes of Bedford. The square takes its name from Marquess of Tavistock, a courtesy title given to the eldest sons of the Dukes of Bedford.
In 1920 the Tavistock Clinic was founded in the square, a pioneering psychiatric clinic whose patients included shell-shock victims of the First World War. In 1946 the Tavistock Institute of Human Relations separated from the Tavistock Clinic. The Tavistock Clinic has since moved to Swiss Cottage.
Richard Lydekker, naturalist, geologist and writer of numerous books on natural history, was born at Tavistock Square in 1849.
Tavistock Square was the scene of one of the four suicide bombings on 7 July 2005. The bomb was detonated by 18-year-old Hasib Hussain on a double-decker bus bearing route number 30; it had been diverted from its normal route along Euston Road because of traffic disruption by the other three bombings at tube stations. The bomb exploded immediately outside the British Medical Association building, many of whose staff came out to give what help they could. The explosion killed 13 passengers, plus Hussain himself. Many others were injured. In September 2018, a memorial honouring the victims and the efforts of those who gave assistance was unveiled in Tavistock Square Gardens, replacing a plaque that had been fixed to the railings outside BMA House, opposite to the new site.
The centre-piece of the gardens is a statue of Mahatma Gandhi, sculpted by Fredda Brilliant and installed in 1968. The hollow pedestal was intended, and is used, for people to leave floral tributes to the peace campaigner and nonviolent resister to oppression in South Africa and British rule in India.
A cherry tree was planted in 1967 in memory of the victims of the atomic bombings of Hiroshima and Nagasaki.
