إدوارد الأول ملك إنجلترا
The medieval architect and castle builder for Edward I of England, Master James of Saint George, also known as Jacques de Saint-Georges d'Espéranche, constructed the castle for Philip I, Count of Savoy. On 23 June 1273 he met King Edward I of England there, and it is likely the castle inspired the later construction of the UNESCO listed castles of north Wales.
