Llywelyn the Great began building the castle at Criccieth around 1230. The placement of a castle allowed access to supplies by sea plus the fortress could have also served as an early warning post from its high vantage point.

A Welsh rebellion in 1404 saw Criccieth Castle sacked and burned. The functional military life of the castle was laid to waste.
