Tenby Castle

[4] The French knight, who was married to the Joan de Munchensi, the granddaughter and heir of the previous Earl of Pembroke, had provided military service to Henry III in the Second Barons' War.

In 1457, King Henry VI gave the Marcher Lordship (and associated Earldom) to Jasper Tudor, his half-brother, who agreed to refurbish and improve Tenby's defences by dividing the cost between himself and the town's merchants.

In the mid 16th century, another large D-shaped tower (named the "Five Arches") was built in the Elizabethan period following fears about a second Spanish Armada.

In 1648 during the Second English Civil War, a unit of Royalists under the command of Rice Powell held a refortified Tenby for 10 weeks until they were starved into surrendering by besieging Parliamentarians.

Tenby Museum & Art Gallery is built on the remains of the castle's domestic building, probably the great hall.
