Deal Castle, built under the order of Henry VIII between around 1540, is smaller than any of the castles visited thus far, but indeed a powerhouse of a place. German architect, Stefan von Haschenperg engineered the defense fortress with six curved bastions - for 360 visibility and incoming firing to be deflected more readily. This is where Anne of Cleves is said to have stayed on route from EU to London to meet up with Henry. Most impressive from an aerial perspective, Henry 8th and others would have never seen during his reign. Many alterations have been made from 16th century onward to keep up with the changing needs of military defense.
