About

Castle ward encompasses the historic core of Grantham, anchored by St Wulfram's Church and the medieval Guildhall. The area features a mix of Georgian and Victorian architecture lining its central streets, with local independent shops and traditional markets operating near the High Street. Grantham House and its gardens are situated by the River Witham, providing a green space within the urban setting.

It functions primarily as a retail and civic centre for the town, containing the council offices and public library. A notable local landmark is the statue of Sir Isaac Newton, a former pupil of the King's School, which is also located within the ward's boundaries.
