Queenborough, United Kingdom

In those days north Kent was divided by open waters and marshes stretching inland. The safest navigation to the open sea was then the route from the Thames into the Yantlet Creek (separating the Isle of Grain from the rest of Hoo Peninsula), and thus into the Swale from the Medway estuary, around the leeward side of the Isle of Sheppey into the Wantsum Channel, navigating past the Isle of Thanet to Sandwich and only then into the open waters of the English Channel. It was thus an easily defensible planned-town centre for the wool trade.

King Edward III had the town renamed after his Queen, Philippa of Hainault, and conferred upon it the rights of a free borough, with a governing body of a mayor and two bailiffs. He granted Queenborough a charter in 1366 and two years later bestowed the duties of a royal borough upon it.

During this period, Queenborough, on the Isle of Sheppey, was an important town for the export of wool, a significant crown revenue. In 1368, the Wool Staple was transferred from Canterbury to Queenborough: Sandwich and Queenborough became the two centres in Kent for wool trading.

The castle was excavated in 2005 by Channel 4's archaeology television programme Time Team.

The town was first represented by two members of parliament in 1572, one of its earlier MPs being the explorer Sir Humphrey Gilbert in 1580. Matthias Falconer of Brabant established the first copperas (iron II sulphate) factory in England at Queenborough in 1579.

King Charles I had the town reincorporated under the title of the "mayor, jurats, bailiffs and burgesses of Queenborough", during which time the population was chiefly employed in the local oyster fishery. However the fort having protected the Swale and Medway estuaries for 300 years was never in fact to realise its function as a garrison, and recorded no active military history. After being seized by Parliamentarians in 1650, after the Civil War, and being considered unsuitable for repair, being of "no practical use" it was demolished during the interregnum.

Not long after this, in 1667, the Dutch captured the new Sheerness fort (then under construction) and invaded Queenborough. The occupation lasted only a few days; though the Dutch caused widespread panic, they were unable to maintain their offensive, and withdrew having captured HMS Royal Charles and burnt numerous other ships in the Thames and Medway. Following this raid on the Medway, much-needed attention was given to the improvement of the naval defences of the Medway, which at length helped strengthen the economy of Queenborough and Sheppey. Some 300 years later, in 1967, The Queenborough and Brielle (the Netherlands) twinning project was established.

The parish church overhaul continued through to 1730, and a number of houses added to the growing town during the 18th century. With the general prosperity of the colonial and mercantile trades of the age, Queenborough thrived. Queenborough Guildhall was completed in 1793.

With the silting up of the Yantlet creek and the Wantsum channel and improved navigation through the Thames estuary to London, Queenborough began to lose its importance, becoming something of a backwater. Daniel Defoe described it as "a miserable and dirty fishing town (with) the chief traders ... alehouse keepers and oyster catchers".

The Royal Navy eventually became less prominent on the River Medway as other dockyards developed and ships grew in size, so that they were largely replaced by prison hulks which would frequently dispose of their dead charges on a salt marsh at the mouth of the Swale, which was subsequently to become known as Dead Man's Island, and can still be found as such, on local maps today. The new fort and harbour developments completed at Sheerness by this time further replaced Queenborough by being better positioned at the mouth of the Medway.
