St Helens Bulwark was a Device Fort constructed on the Isle of Wight between 1539 and 1545 to protect the adjacent anchorage. The site saw only brief service and has since been lost.
History
In 1533, King Henry VIII broke with Pope Paul III in order to annul the long-standing marriage to his wife, Catherine of Aragon, and remarry. Catherine was the aunt of King Charles V of Spain, who took the annulment as a personal insult. As a consequence, France and the Empire declared an alliance against Henry in 1538, and the Pope encouraged the two countries to attack England. An invasion of England now appeared certain; that summer Henry made a personal inspection of some of his coastal defences, which had recently been mapped and surveyed: he appeared determined to make substantial, urgent improvements.
Henry VIII gave instructions through Parliament in 1539 that new defences were to be built along the coasts of England, beginning a major programme of work that would continue until 1547. The order was known as a “device”, which meant a documented plan, instruction or schema, leading to the fortifications later becoming known as the “Device Forts”. The initial instructions for the “defence of the realm in time of invasion” concerned building forts along the southern coastline of England, as well as making improvements to the defences of the towns of Calais and Guisnes in France, then controlled by Henry’s forces. Commissioners were also to be sent out across south-west and south-east England to inspect the current defences and to propose sites for new ones. After the initial invasion scare, Henry moved back onto the offensive in Europe in 1543, allying himself with Spain against France once again.
St Helens Bulwark was built as part of this programme of work, at some point between 1539 and 1545, to protect the anchorage of St Helens on the east side of the Isle of Wight. In 1545, the French raided the island, during which the fort may have been captured. It appears to have fallen out of use and there is no mention of it after 1660; a coastal artillery battery was built on top of the site in the 19th century and no trace now remains.
