The discovery of Tutankhamun's tomb in 1922 began at Highclere Castle in Hampshire, the home of Lord Carnarvon, who paid for Howard Carter's search in the Valley of the Kings. This route follows the money and the dig, from Hampshire to Luxor and Cairo.
It runs from the 1907 digs at Deir el-Bahari to the first step of KV62, Carnarvon's death in Cairo, his burial on Beacon Hill and the museum where the treasures ended up. One caveat: the exact site of the Cairo hotel is not pinned.
Jane Austen's life ran through four places in southern England: the Hampshire village of Steventon, the spa city of Bath, the cottage at Chawton and, at the end, Winchester Cathedral. Bath's Pump Room and Assembly Rooms also appear in her novels Northanger Abbey and Persuasion.
The route follows her from the rectory where she grew up in 1775 to her grave in 1817. The Steventon rectory is gone, so that pin is approximate; the other four places can all be visited today.
Downton Abbey is set on a fictional Yorkshire estate between 1912 and 1925, but its great house stands in Hampshire and its village in Oxfordshire. This route follows the story, from the Titanic news of series 1 to the royal visit of the 2019 film, to the real places behind it.
It takes in Highclere Castle, Bampton's church and library, a prison in Lincoln, castles in Scotland and Northumberland, the Ealing stage where the kitchen was built, and the film's parade village and York streets. Lacock's pin marks the village, as the sources name no exact spot.
