In the medieval period, the five-towered fortress was actually known as Castrum Leonis or Castle Lyons because it had a lion motif carved into the stonework above its main gate.
Keskiajalla viisitorninen linna tunnettiin nimellä Castrum Leonis tai Castle Lyons, koska sen pääportin yläpuolelle oli kaiverrettu leijonahahmo.
