Princess Eugenie's wedding at St George's Chapel this autumn will follow that of her cousin, Prince Harry, in May.
The stunning 15th century gothic church is set in the Lower Ward of the Queen's beloved Windsor Castle.
Steeped in history, it offers a slightly more intimate venue for royal nuptials, but one that is still appropriately grand.
It usually holds around 800 guests and is convenient for the Queen, now 91, and the Duke of Edinburgh, 96, who spend a great deal of time at home in the Berkshire castle.
Receptions for both Harry and Meghan Markle's wedding and that of Eugenie and fiance Jack Brooksbank
could be held in the castle's 180ft (55m) long St George's Hall, traditionally used for glittering state banquets.
Here's a look at some of the royal weddings which have taken place in the Chapel:
Peter and Autumn Phillips
The last royal wedding at St George's Chapel was Peter Phillips - son of the Princess Royal - who married Canadian Autumn Kelly in 2008.
The royal family traditionally gather together on the vast West Steps afterwards for photographs.
The Prince of Wales and the Duchess of Cornwall
Charles and Camilla were blessed, rather than married, in the Chapel in 2005.
Their actual civil ceremony was held in private, down the road in Windsor's Town Hall.
Camilla - who, like Charles, was a divorcee - switched her outfit for the religious blessing.
The Queen, who is head of the Church of England, did not attend the civil ceremony but was there for the televised blessing in the Chapel conducted by the Archbishop of Canterbury.
The Earl and Countess of Wessex
In 1999, Eugenie's uncle, the Earl of Wessex, married Sophie Rhys-Jones, now the Countess of Wessex, at St George's.
The couple waved to onlookers as they took a carriage ride through the town.
Here are some of the other events St George's is known for:
Order of the Garter ceremony
It is the Chapel of the Order of the Garter, the senior order of chivalry in England, established in 1348 by Edward III.
Each year in June, royals who are Knights and Ladies of the Garter proceed in carriages from the state apartments down the hill to the chapel for the traditional Order of the Garter ceremony.
They dress in their Garter robes - heavy blue velvet capes and black velvet hats with elaborate white ostrich plumes.
The church has been the setting for many historic funerals including the Queen Mother's private committal service following her Westminster Abbey funeral in 2002, and in the same year, Princess Margaret's small, private funeral.
The funeral of the Queen's father, King George VI, took place at St George's in 1952.
