This wall was the main layer of defence, and it tended to be incredibly strong-for example, the curtain wall of Caerphilly Castle in Wales was more than 2 metres (thatâs more than 6ft) thick.ffectively it was âa castle in a castleâ. This new design had the strongest defences imaginable, and attackers were barely ever able to capture it. The design can be seen in Wales-a great example is Beaumaris Castle, pictured above.
