wales: st davids
On the western tip of Wales lies the village (officially a city) of St Davids. Its cathedral was founded by Welsh patron saint David in the fifth century, and became an important place of pilgrimage in the middle ages. (For a while two pilgrimages to St Davids were deemed equal to one to Rome.)
The surrounding rugged and windswept peninsula culminates in St Davids Head, which the Romans dubbed the Promontory of the Eight Perils. (Not sure what these were, but it's obviously not an easy place to reach by ship.)
