Is this the castle of the Holy Grail? Peel Castle on the Isle of Man has been a monastic retreat, a fortress and home to a Viking king. Neolithic, Bronze Age, and Celtic remains have been excavated in recent years and a visit to Tynwald Hill and the House of Keys reveals evidence of the island’s Viking heritage in the parliamentary system and language. We explore the islander’s love of folklore and their healthy appetite for locally smoked kippers.
