Caledonia - Latin name given by the Romans to the land in today's Scotland

"Caledonia is the Latin name given by the Romans to the land north of their province of Britannia, beyond the frontier of their empire, roughly corresponding to modern-day Scotland. However, southern Caledonia, as far north as the Antonine Wall, was part of the Roman Empire for some periods of time. The etymology of the name is probably from a P-Celtic source. Its modern usage is usually as a romantic or poetic name for all Scotland in general. - Wikipedia"
