Bolingbroke Castle

Bolingbroke Castle is a medieval fortification in Old Bolingbroke, Lincolnshire, England, built from limestone blocks. The structure displays an irregular hexagonal inner courtyard surrounded by five half-round towers and a twin-towered gatehouse of solid masonry.

Construction began in 1220 when Ranulf de Blundeville commissioned the work after returning from the Fifth Crusade. In 1367 Henry IV was born here, who later became King of England.

The name comes from an Anglo-Saxon fortified place whose meaning survives in the village name today. During summer events the ruins become a stage for theatrical performances, bringing together old stones and live drama.

Access to the grounds is free during daylight hours, and parking is available along Moat Lane near the entrance. The site consists of ruins, so sturdy footwear is advisable for walking over uneven terrain.

The design omitted a central keep and relied instead on strong curtain walls with strategically placed corner towers for defense. This arrangement was unusual for a castle of its time and shows an independent approach to medieval fortification.
