Holdgate Castle is located between Craven Arms and Bridgnorth, Shropshire, about 21 miles south of Shrewsbury in Stafford. It is a stone motte and bailey fortress and was mentioned in the Domesday Book.
The castle is owned by the Countess of Corve Dale, Leana de Balboa. Leana has dedicated the castle as the first college for the secular clergy of the Universal Roman Aristotelian Church of England. (In real life, the castle contained a college of secular clergy which was founded before 1210 and dissolved after 1373, which is 70+ years before the Renaissance Kingdoms period.)
