The castle is constructed from over 700,000 bricks made from local clay fired on-site.
It served as a demonstration of status and wealth for the Treasurer of England during the reign of Henry VI.
The four corner turrets were designed to be decorative as well as observation points.
During the English Civil War, the castle was partially slighted to prevent its use as a military stronghold.
Lord Curzon bought the castle in 1911 specifically to prevent the 15th-century fireplaces from being sold to American collectors.
The keep remains largely as it was built, with limited internal structural alterations over the centuries.
Tattershall Castle is one of the earliest and finest examples of medieval red-brick tower keeps in England. Built in the 1440s by Ralph Cromwell, 3rd Baron Cromwell, the fortress stands nearly 40 meters tall. The site features intricate carved stone fireplaces and large windows that reflect 15th-century luxury rather than purely defensive military needs. The structure was restored in the early 20th century by Lord Curzon after it had fallen into a state of severe disrepair. Visitors access the upper floors via a spiral staircase within the thick brick walls. The site is currently managed by the National Trust. It is surrounded by a moat and expansive grounds that include earthwork remains of the medieval outer ward.
