York Minster, an Anglican cathedral in York, tops the list with an impressive total of 210,501 posts. Season six will see Prince Charles and Camilla Parker Bowles marry, with the reimagining of their wedding at St George’s Chapel having been filmed at York Minster.

Heading over to London’s business district, Canary Wharf takes second place with 80,265 posts. The financial hub was transformed into a Canadian city and 1990s Chicago earlier this year for filming of season six. Dominic West, who plays Prince Charles, could be seen alongside extras, playing royal fans, welcoming Charles to Canada.

The third most Instagram-worthy location in the rankings is the University of Greenwich with 63,951 posts. This picturesque university is situated in London and was used for a scene in season three, which sees Lord Mountbatten passing on bad news to Prince Charles in the courtyard of Buckingham Palace.

Featuring in 49,664 posts is Manchester’s Northern Quarter, putting it in fourth position. The heart of Manchester’s alternative and bohemian culture, the area doubled as a steamy 1980s Manhattan for Princess Diana’s first official trip without Prince Charles to New York in season four.

Waddesdon Manor in Buckinghamshire takes the fifth spot with 48,871 posts. This majestic National Trust building is often used as a substitute for Buckingham Palace on the show and doubles as The Ritz in season five, when the Al-Fayed family acquire the iconic hotel.

Placing sixth, with 47,733 posts, is the second cathedral in the rankings, Winchester Cathedral. The magnificent structure stood in as St Paul’s Cathedral for Winston Churchill’s funeral in season three and is also rumored to be standing in for Westminster Abbey for Princess Diana’s funeral in the final season.

The seventh most ‘Instagrammable’ location is yet another cathedral, Ely Cathedral in Cambridgeshire. Featuring in 46,983 posts, this marvel of medieval engineering doubled as Westminster Abbey for Queen Elizabeth II and Prince Philip’s wedding in season one.

The rankings now return to the North of England as Liverpool Docks makes the eighth spot with 45,724 posts. The maritime city’s famous waterfront was a substitute for Washington DC for Princess Margaret’s visit to meet President Johnson in season three.

Ninth place goes to the Lyceum Theatre in London’s West End with 37,194 posts; Queen Elizabeth II and Prince Philip attend a performance at the theatre in season one. The historic performing arts venue was also used to film a recreation of Princess Diana and Mohamed Al-Fayed watching Swan Lake at The Royal Albert Hall in season five.

Rounding off the rankings is Hatfield House in the tenth spot with 36,573 posts. Located in Hertfordshire, this Jacobean house has been a prominent feature in many seasons of the show; its lavish rooms serve as the perfect double for the opulent interiors of Buckingham Palace.

Commenting on the findings, a spokesperson from CasinosSweeps.com said: “Hit shows such as The Crown are helping the niche form of film tourism flourish. Not only do TV series provide entertainment to many, but they also financially benefit many filming locations. The featured spots often see a rise in visitor numbers, giving them an economic boost.

With the historical drama coming to an end this season, it will be interesting to note whether the filming locations starring in season six will see an increase in tourism. It could be a key indicator of how well the season has performed with audiences.”
