King Arthur's legend has no single home: he is conceived at Tintagel and holds court at Caerleon, Cadbury Castle is claimed as Camelot and Glastonbury is linked to Avalon. The route follows Geoffrey of Monmouth, Malory and others from Merlin's dragons to the sword returned to the water.
Every pin marks a real place that tradition has attached to an episode, not a site proven by history, and each stop says where the link is doubted.
The Mabinogion, Wales's medieval collection of myths, is set across Narberth in Pembrokeshire, Harlech, Tomen y Mur, Segontium and Dinas Emrys in Gwynedd. Its tales of Rhiannon, Branwen, Lleu and two fighting dragons have all been tied to real hills, forts and castles.
This route follows three of the Four Branches and two native tales, from Pembrokeshire to Gwynedd. Several identifications are traditional rather than proven, and each stop says so.
Stranger Things' Hawkins, Indiana, is really small-town Georgia: the town square in Jackson, a shuttered psychiatric hospital near Atlanta, a dead shopping mall in Duluth. The stand-ins also include a mansion in Rome and a Vilnius prison playing Kamchatka; in the story, a boy vanishes and a girl walks out of the woods.
This route follows the real stand-ins, from the laboratory where the story begins to the quarry, the school, the Starcourt Mall, the mansion that became the Creel House, and the Vilnius prison that stood in for Kamchatka.
Much of Game of Thrones' North was filmed in Northern Ireland. Winterfell, its godswood, Castle Black, the Kingsroad and a fishing harbour that played Pyke were all real ground dressed as Westeros, and a basalt hillside above a small Antrim village hosts the first execution of the series.
The route runs in the order the episodes aired: the deserter's beheading above Cairncastle and the Winterfell of Castle Ward, then the quarry that held Castle Black and the Wall, the godswood, the Kingsroad beech avenue and the harbour where Theon Greyjoy comes home. The last stop is the Moneyglass estate, where a bigger Winterfell was built for the second season and used again for the eighth season's battle. Almost everything here is exterior: Winterfell's great hall was a soundstage set.
After a first season in Malta, the show crossed the Adriatic to a walled city. Dubrovnik's two-kilometre ramparts, the fortress above its western gate and its late-medieval streets played King's Landing for everything the effects departments could not invent: the name-day combats, the riot at the gate, Cersei's walk of atonement.
Eight stops run in the order the episodes aired — Lovrijenac and the Pile Gate in the second season, the Rector's Palace when Dubrovnik doubled as Qarth, the Red Keep's gardens at Trsteno and the Meereen stand-in at Klis in the third and fourth, and the Jesuit stairs where the fifth-season finale was shot in October 2014. Only the exteriors live here: the Red Keep and the Sept of Baelor were computer-generated.
King Pelias sends his nephew Jason to fetch the Golden Fleece from Colchis, at the far end of the Black Sea, hoping he will never come back. Jason builds the Argo, gathers the greatest heroes of his day, Heracles among them, and sails east. Apollonius of Rhodes told the voyage in his Argonautica in the 3rd century BC, and he filled it with real coasts, harbours and local legends.
This route follows the outward voyage to Colchis. The way home is left out: ancient writers sent the Argo back by wildly different routes, up rivers into the Adriatic and even across Libya. The heroes and the fleece are myth; the shores, islands and ancient cities are real. Quotations are from R. C. Seaton's 1912 translation.
