The castle at Carisbrooke on the Isle of Wight had strategic importance in the face of a possible Spanish invasion. Modifications were made to the inner bailey in 1587, and more extensive bastions and outer works were constructed between 1597 and 1602 to the design of the Italian FederigoGiainibelli. These included the creation of arrow-headed bastions.
