The story is about a Rolls traveling with the Princess and used by her parents for her wedding day.

In the course of this week, the Royal Court has previously disclosed all details of the protocol and program of the day in which Princess Leonor was to be sworn in to the flag. Even the itinerary of the Royal Family and their convoy was publicly available, only some details were not disclosed for security reasons. Among them, and even though it could be assumed, the Royal Court did not disclose in which vehicles the Kings, Princess and her sister would be traveling. It could have been assumed that they would use one of the three Rolls Royce Phantom IVs owned by the National Heritage. Three unique cars out of a total of 18 produced by Rolls Royce in the 50s.

Only 18 in the world.

They were originally commissioned'. 'Queen Isabella II and the Duke of Edinburgh, but Franco fell in love with them and ordered three cars. In no way was this a gift from Hitler to the royal family or anything like that, as one might have heard. As a curious fact, one of the 18 cars belongs to the King of Morocco.

The one small detail that sets them apart from the Rolls Royce sold to regular buyers is that the symbol on the hood, known as the Spirit of Ecstasy, bows as a sign of respect. Only on the royal''cars the Spirit of Ecstasy bows. It's a small detail that distinguishes the Rolls Royce cars designed for royal families around the world.

A little after 10am the mystery was solved.

The royals traveled in an enclosed Phantom IV, while the princesses sat right behind them in a convertible. However, for security reasons, it was decided to use the same solution as at the royals' wedding - using a glass enclosure that allows them to be seen without risking a terrorist attack. A Rolls Royce Phantom IV during the ride to the ceremony. In 2004, on the occasion of the Kings wedding, a Madrid coachbuilder secured the car and made a glass cover, which they were already using, and which can be removed. It is made of bulletproof glass, and at that time it was decided to''manufacture it because of the proximity of the March 11 terrorist attack.

The two cars are National Heritage vehicles in the service of the Army, so the license plates they have contain the letters ET and are not used in official ceremonies.
