Unveiled in 1954 by Sir John McNee, then President of the BMA, and dedicated by Geoffrey Fisher, the Archbishop of Canterbury, it became a Grade II* listed structure in 1998.

Thomas Cubitt continued the construction of the western half of the square in 1825–26, following – though improving on – Burton's general design for the eastern frontages.

[b][2] Tavistock House was demolished in the early 20th century and from 1911, was replaced by the current building designed by Edwin Lutyens as the British headquarters of the Theosophical Society.

The World War I memorial was dedicated by Randall Davidson, Archbishop of Canterbury, on 13 July 1925, the day when the BMA's new building was officially opened by King George V and Queen Mary.

[12] The memorial comprises a bronze fountain of intertwined serpents set in a lead-lined circular pool and surrounded by four statues representing "Sacrifice", "Cure", "Prevention" and "Aspiration".

[14] The side of the stone fountain surround is inscribed with the words IN MEMORIAM 1939–1945, and a bronze dedicatory plaque reads IN HONOUR OF THE MEDICAL MEN AND WOMEN OF / THE BRITISH EMPIRE AND COMMONWEALTH OF NATIONS / WHO GAVE THEIR LIVES IN THE SECOND WORLD WAR.
