Tattershall Castle is a fifteenth-century fortress built by Ralph, Lord Cromwell, between 1433 and 1439, representing one of the finest examples of brick construction from the medieval period in England. The castle is dominated by a substantial brick-built keep or tower house, which stands approximately 110 feet high and demonstrates the sophisticated masonry techniques employed in its construction, with decorative diaper patterning and multiple storeys featuring large windows and ornamental brick details. The site also incorporates the adjacent College of the Holy Trinity, founded by Cromwell in 1440, which reflects the patron's status and piety during the later medieval period. The complex exemplifies the transition from military fortification towards the more domestic and residential character of late medieval aristocratic architecture, though it retains defensive capability through its formidable tower structure and moated position within the Lincolnshire landscape.
