Royal residence and war machine

The northern gatehouse was planned as an impressive royal residence, not simply an entry point. Reconstructions at the site reveal the intended scale and beauty of apartments that were never finished. A completed Beaumaris would have forced an invader either to avoid the district or commit to a slow siege. The battleship comparison explains why larger weapons alone do not determine the outcome, since fire control, hit probability, protection, and accumulated damage also matter. Castles similarly reduce an attacker's chances and buy time without becoming invulnerable. The example of attackers posing as carpenters shows another limit: access, trusted roles, and the large amount of timber inside a stone castle could undermine brute-force defenses.
