The castle is very well fortified, and truly a prime example of a true traditional castle. Alongside it's practicality, it remains to be a beautiful piece of historical architecture despite being admittedly bland. It's impressive build quality will outlive most modern structures. Being an Irish castle, and having the critics be of Irish heritage there is a clear bias here. It would also just be a badass zombie apocalypse bunker.
The final Towers out of Ten rating is 9/10, taking into account the castle-ship criteria and person opinion.
