Queenborough Castle, also known as Sheppey Castle, is a 14th-century castle, the remnants of which are in the town of Queenborough on the Isle of Sheppey, Kent in England. The castle and the associated planned town were built on the orders of King Edward III from 1361 and named in honour his wife, Queen Philippa. It was the first concentric castle to be built in England, and the only royal castle to be new-built in England during the Late Middle Ages. Overlooking the Swale, then an important waterway approaching the River Medway, Queenborough Castle formed part of the country's coastal defences until 1650 when it was declared to be unfit for use and was almost completely demolished shortly afterwards. The site is now a public park and the only visible remains are some low earthworks.
History
Background
The history of the castle begins in 1361, when King Edward III bought land on the Isle of Sheppey from the manor of Rushenden at the little fishing hamlet of Bynne (or Bynnee); two houses which stood on the site had to be demolished and their occupants rehoused. The stated role of the castle was "for the defence of the realm and for the refuge of the inhabitants of the island". The 1360s were an uneasy peaceful interlude in the Hundred Years' War, brought about by the Treaty of Brétigny in May 1360. It has been suggested that the new castle was more of a palace-fortress, intended as a refuge for the royal family from the Black Death which had arrived in England in the middle of the previous decade. However Queenborough's location commanding the confluence of the Swale and the River Medway, then an important route into the Thames Estuary, together with the contemporary refurbishment of Hadleigh Castle on the opposite side of the Thames demonstrate that there was a strategic consideration. Moreover, there had been destructive French raids on the south coast ports of Rye and Winchelsea in March 1360.
Construction Oversight of the construction has been credited by various sources to either master masons John Box or Henry Yevele, or to William of Wykeham. The work required some 1,600 craftsmen and labourers, and was completed by about 1367 at a cost of some £20,000. The castle was built to a radical concentric design, the first of its type to be built in England. It consisted of a large circular building, described as a rotunda or shell keep, buttressed by six projecting towers and having a central circular courtyard. This main building was surrounded by an outer circular curtain wall and a moat. It is possible that the design was influenced by that of Bellver Castle, which had been built in Mallorca between 1300 and 1311 for King James II of Majorca. Queenborough was one of the first English castles built to withstand siege artillery and to mount guns itself, and the last royal castle to be built in England during the Late Middle Ages. Originally, water was channelled from the roofs through lead piping into storage cisterns, but in 1393 a contractor spent sixty weeks digging a deep well in the centre of the courtyard.
14th to 16th centuries
The first constable of the castle was appointed in 1365 before its completion, with instructions to arm it and make it defensible. In the same year, "two great guns and nine small ones" were sent from the cannon foundry at the Tower of London to Queenborough, taking priority before even Dover Castle. Upon the completion of the castle, it was visited by Edward III who created a royal charter for the town which was being laid out close by, naming it Queenborough in honour of his queen consort, Philippa of Hainault. The office of Constable of Queenborough Castle was evidently a prestigious one and those appointed held high rank, notable constables included John of Gaunt, Duke of Lancaster (from 1377) (King Edward's third surviving son), Robert de Vere, Duke of Ireland (from 1385), Thomas Arundel, Archbishop of Canterbury (from 1409) and George Plantagenet, 1st Duke of Clarence (from 1461). Queenborough was one of the residences which Edward III visited frequently during the latter part of his reign. On 21 April 1450, Queenborough Castle was attacked by a French force in a coastal raid, and in July of the same year, easily repelled an attack by Jack Cade and his rebels, during which Cade himself was wounded. King Henry VIII repaired the castle in 1536, and an account written in 1629 describes seeing the coat of arms of Queen Elizabeth I on the wall of the castle's great hall accompanied by a laudatory verse in Latin, exhorting her to "live a virgin and a lion reign".
17th to 19th centuries During the English Civil War, Queenborough Castle was held by the Royalists, but after the execution of King Charles I in 1648, the castle came into the possession of the Commonwealth and trustees were appointed to look after it. In 1650, Parliament appointed commissioners to survey the properties which they had acquired from the crown. The report on the condition of Queenborough Castle described it as "much out of repair, and no ways defensive by the commonwealth" and judged that it was "not fit to be kept, but demolished". The castle was sold to one John Wilkinson for £1,792, twelve shillings and one halfpenny; he demolished the entire castle down to the foundations and sold the materials. In 1723, the Royal Navy surveyed the well which had survived the demolition and found it to be 200 feet (61 metres) deep and lined with Portland stone. After further deepening, they were able to extract “good, soft, sweet and fine” water for the dockyard at Sheerness. In 1860, the Sheerness branch line railway opened, having cut through the eastern part of the site and a pump house was built over the well, as the water was needed for the locomotives. A school was built over the western side of the site.
