This Square took its name from Lieutenant-General John Manners (1721-1770), Marquis of Granby, one-time the Master-General of the Ordnance.

[1] A part of a very rare and highly important 1765 wall map of Devonshire by Benjamin Donn. Drawn in twelve panels, this map covers the entirety of Devonshire or Devon from the English Channel to Barnstaple (Bideford) Bay and from Cornwall to Somerset at a scale of 1 inch to 1 mile. Donn also incorporates large insets of Exeter (showing the college), Plymouth, Plymouth Dock, Stoke Town, and the Isle of Lundy. Benjamin Donn (1729 - 1798), sometimes known as Benjamin Donne, was a British cartographer, surveyor, and mathematician active in England during the middle to late 18th century.
