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.
York has been defended by walls since Roman times, and this walk strings together six places around them: the Multangular Tower, York Minster, Clifford's Tower, Micklegate Bar, the Shambles and Walmgate Bar.
Each stop is a moment in the city's story, from a Roman fort built around 71 AD to a siege in 1644.
Hadrian's Wall ran 73 miles across northern England, from Segedunum at Wallsend on the Tyne to Bowness-on-Solway, begun in AD 122 under Emperor Hadrian. Six stops, from Chesters and Housesteads to Vindolanda and Birdoswald, show how it was built, changed and garrisoned.
The route follows the wall west, from Roman forts to the Solway shore. The exact western end of the wall near Bowness is not known.
Bridget Jones's Diary is set and filmed around Borough Market in south London, with Shad Thames, the Royal Courts of Justice and Cornhill on the way. The film moves Bridget from Holland Park to a flat above the Globe pub, where the story begins.
This route follows the film's story through eight London and country locations: the book launch at the ICA, the first date at Shad Thames, the mini-break at Stoke Park, the anniversary party at Syon House and the snowy finale. The film was shot over six weeks in and around London in 2000.
Where The Last Kingdom is set: Bamburgh Castle in Northumberland, Viking York, the Somerset marshes at Athelney and the battlefield at Edington, the real ground of Uhtred's wars. A Saxon boy raised by Danes, he fights for Alfred and against him, and each stop is set against what history records.
The television series adapts Bernard Cornwell's Saxon Stories; where a stop follows a particular novel or series, the point says so. The show was filmed mainly in Hungary, so the places below are the real settings of the events, not the filming locations.
Peaky Blinders mostly filmed its 1919 Birmingham on Liverpool's Powis Street, the Worth Valley Railway and Bradford's Little Germany. Tommy Shelby's gang rules Small Heath.
The route follows the story from Small Heath, through the Liverpool street that played Watery Lane, a Yorkshire railway, Aunt Polly's village and the Black Country, to Bradford's warehouses, Tommy's country house and the beach where series 4 ends. Most pins mark stand-ins, labelled as such.
The Galar region is Britain played back as a game: a fictional land inspired by the United Kingdom, dotted with landmarks that recall Bath and York, crowned by a London of clock towers and football-stadium gyms. Eight gym cities, eight badges, and then the Champion's Cup in Wyndon, where Leon waits and the Darkest Day breaks.
This route walks the real Britain behind that map, south to north and then beyond: a chalk giant, a lighthouse, Roman baths, a minster, a national stadium and a clock tower, plus the two downloadable lands, the Isle of Man and the snows of Scotland. Every identification is a fan or developer reading, never confirmed in the games, so every pin here is speculative.
A famous American actress walks into a Notting Hill travel bookshop, and its shy owner falls for her: that is the whole of Notting Hill, and somehow it is enough. Hugh Grant stammers, Julia Roberts glows, and London plays itself, from the market street of Portobello Road to a midnight garden and a press conference at the Savoy.
The route follows the film in story order, from the bookshop at 142 Portobello Road and the blue door at 280 Westbourne Park Road to the Ritz, a birthday party, the private garden, the Henry James set at Kenwood House and the Savoy finale. The flat interiors were studio sets and the garden is private, so some pins are for looking rather than entering.
Assassin's Creed Valhalla brings the Viking Eivor and their clan to Anglo-Saxon England, where Hytham asks for help ridding the land of the Order of the Ancients. Following tip-offs from an informant who signs himself the "Poor Fellow-Soldier of Christ", Eivor hunts Order members from Grantebridge to Jorvik and Wincestre.
The route visits the real places behind the game's: Cambridge, where the jarlskona Soma takes back her town; York, the capital of Viking Britain; the docks of Repton, where the Great Heathen Army wintered; Alfred's Winchester; the battle at Chippenham in 878; and Athelney, where the informant's identity is finally revealed. All six can be visited today.
