Upnor Castle Upnor Castle goes towards the genre of Henrician cosastal forts but is definitely an Elizabethan accessory for the chain. It had been begun in 1599 to protect the method of the brand new dockyard at Chatham, laying two miles away close to the estuary from the River Medway. Mister Richard Lee interrupted his focus on the fortifications at Berwick-on-Tweed, in the future and style this fort, but construction pulled on for eight years. In 1599-1601, Upnor was enlarged however it needed to hold back until 1667 to manage enemy action. For the reason that year, the Nederlander, under Admiral p Ruyter, sailed in to the Medway and hang fire to a lot of the British fleet. The castle was not able to provide any effective resistance as well as in the year after a brand new chain of protection was begun, Upnor being consigned towards the role of storehouse and magazine. Military occupation of 1 kind or any other ongoing until world war ii. As initially created, the castle composed an oblong blockhouse, occur the center of an inquisitive screen wall terminating each and every finish inside a stair turret. This building provided accommodation for that garrison, defense being concentrated upon the reduced, pointed bastion facing the Medway. Pointed bastions were devised like a defense against artillery in Renaissance Italia. Mister Richard Lee built several along his new ramparts at Berwick, however the Upnor bastion doesn't have the characteristic "arrowhead" plan caused by a narrow collar. Its riverside setting made that unnecessary. However, since only one for reds from the bastion faces upriver, there have been inadequate gun emplacements to fireplace effectively with an approaching fleet-it was the issue in 1667. The late Elizabethan enlargement provided protection around the landward side. A walled courtyard was produced while watching blockhouse, with towers in which the new curtain joins the screen wall. The courtyard is joined via a gate tower retaining the standard obstacle of the drawbridge.
