Hurst Castle

Hurst Castle stands on Hurst Spit, a narrow shingle bank that juts into the Solent near the Isle of Wight. Built between 1541 and 1544 on orders of Henry VIII, it was one of four Device Forts meant to guard England against invasion. The original design had a central keep and three bastions, with space for up to 71 guns. By 1547 it held 26 pieces, including brass sakers and iron demi-cannons. The fort defended the western entrance to the Solent, a key waterway leading to Portsmouth and Southampton. Over time, its role shifted as new threats arose and old ones faded. The castle played a part in the English Civil War when Parliament held it and briefly detained Charles I before his execution. In the 18th century it fell into disrepair and became a haunt for smugglers along the spit. Repairs came during the French Revolutionary and Napoleonic Wars, when heavier 24-pounder guns were installed. By the 1850s fears of invasion led to even larger 32-pounder guns and new batteries. Later, in the 1860s and 1870s, massive 12.5-inch rifled guns were mounted in long granite batteries beside the older structure. Today visitors walk through the layered defences of the fort, from the Tudor keep to the Victorian batteries. The high lighthouse of 1867 still guides ships into the Solent. The spit shelters saltmarsh and mud flats, offering quiet paths beside the sea. The castle’s eastern wing shows signs of strain from coastal erosion. English Heritage and local supporters work to protect the site, which remains open to the public.
