The Antiqua maneria (ancient manors) were the original 17 manors belonging to the Earldom of Cornwall.
After March 1337 these manors passed to the new Duchy of Cornwall which was created by King Edward III to give financial support to his son Edward, the Black Prince (1330 - 1376).
The table below shows the 17 Antiqua maneria including the number and status of Customary tenants in the early fourteenth century: the manors vary greatly in size and importance. The parishes stated are the modern parishes rather than those in existence in the 14th century.
