'London Street Names' by Gillian Bebbington (1972) reveals that, 'Salisbury Court and Square mark the site of the medieval palace of the Bishops of Salisbury, where they stayed when summoned to London to attend Parliament, or on other business. Salisbury Court was its main carriage entrance, and the Square was the central courtyard. In 1564 the Bishop sold the house to Sir Richard Sackville, father of Sir Thomas Sackville, Earl of Dorset (who wrote 'Gorboduc', the first English tragedy in blank verse): hence Dorset Buildings and Rise leading out of the Square. The house was destroyed in the Great Fire of 1666.'
