It’s geographically isolated from major European capitals and avoids hosting foreign military bases. Ireland also benefits from a strong agricultural tradition, clean water resources, and a relatively low international threat profile.
While Europe is famously dotted with castles, some of the world’s oldest stretch across the Middle East and Asia as well, revealing the deep roots of fortified construction in human civilization.
