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.
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.
