All the photos from Russia's first royal wedding in more than a century

The Russian royal family has celebrated its first wedding in over a century, with the marriage of Grand Duke George Mikhailovich Romanov and his Italian wife, Victoria Romanovna Bettarini.

The Grand Duke is a descendant of Russia's long-defunct Imperial family, the Romanovs. His great-grandfather was Grand Duke Kirill Vladimirovich, who was a first cousin of Russia's last emperor, Nicholas II.

The couple wed on Friday, October 1 at St Isaac's Cathedral in St Petersburg, in a grand affair that will span two days.

According to Tatler, the traditional religious ceremony will be followed by a reception at the St Petersburg Ethnographic Museum and a brunch at Konstantinovsky Palace, and catering by 'Putin's Chef', Yevgeny Prigozhin.

Opting for a simple, long-sleeve, satin gown, Victoria chose to decorate her look with accessories, including a glittering diamond Lacis Tiara by the House of Chaumet.

The tiara is reportedly a modern reimagining of the Russian kokoshnik tiara, and the same style worn by Princess Eugenie at her 2018 wedding.

Victoria's tiara is 27.03 carats, featuring two central diamonds of 5.02 and 2.21 carats respectively, as well as 438 pavé diamonds.

The bride's dress also featured a long train, which required as many as six bridesmaids and helpers to carry into the Cathedral.

A suite of other royals attended the lavish ceremony, including Queen Sofia of Spain, Princess Leia of Belgium, and Sheikh Mohammed bin Hamad bin Khalifa Al Thani.

Victoria's father, Ambassador Roberto Bettarini, an Italian diplomat, walked her down the aisle and accompanied her as she entered the wedding reception.

The royal and his wife decided to return to St Petersburg for their big day, despite the duke being born in Madrid and spending the majority of his life living in Spain and France.

He first visited Russia in 1992 and later moved to Moscow to be closer to family. He now and works there, with most of his business centred around philanthropic projects.
