Landguard Fort

Landguard Fort is one of England's finest surviving examples of coastal defence fortification, strategically positioned at the mouth of the Rivers Orwell and Stour near Felixstowe, Suffolk. With roots dating to the 16th century, the current structure evolved from a 1711 artillery fort extensively remodelled in the 19th century, and served through both World Wars including an anti-aircraft role in World War II. The fort is historically significant as the site of England's last opposed seaborne invasion in 1667, when Dutch forces were repulsed by the Royal Marines in their first land battle. Visitors can explore restored underground magazines, dimly lit casements, and Cold War defence headquarters, while the adjacent Felixstowe Museum in a former submarine mining station provides additional context. The fort remains an active heritage site managed by the Landguard Fort Trust in partnership with English Heritage.
