Lincolnshire
Grimsthorpe Castle
Grimsthorpe Castle has been in the Willoughby de Eresby family for five hundred years. It was granted by Henry VIII to William, Baron Willoughby de Eresby on the occasion of his marriage to Maria de Salinas, lady-in-waiting to Katherine of Aragon, in 1516. Rising majestically from the undulating landscape of south Lincolnshire, the castle is set in extensive parkland of great antiquity. The oldest part of the castle, King John’s Tower, was built in the early 13th century. It is the main front which gives the castle its grandeur and dramatic scale. The final masterpiece of Sir John Vanbrugh, architect of Blenheim Palace and Castle Howard, it was commissioned in 1715 by Robert Bertie, Baron Willoughby de Eresby, to celebrate the family’s elevation to Dukes of Ancaster and Kesteven.
The magnificent parkland contains many veteran oaks, and some ancient oaks that predate the planting carried out in the 1700s.
We were fortunate enough to be invited to gather some acorns in 2018 and 2022 and have a few Grimsthorpe trees growing from a lovely veteran oak.
