The Queen’s unusual Duke of Lancaster title has been used in the British monarchy since 1399.
The title comes hand-in-hand with the Duchy of Lancaster which is an estate consisting of 19,000 hectares of agricultural, commercial and real estate holdings in England and Wales.
The privately-owned estate predominantly involves land-based in Lancashire, Yorkshire, Cheshire, Staffordshire and Lincolnshire.
The estate also includes a large commercial portfolio in the Savoy precinct in the Strand in London.
According to the latest official figures, the Duchy of Lancaster is worth £549 million which forms an essential part of the Royal Family’s income.
