Princess Leonor de Borbón is preparing for the day she is crowned Queen of Spain.
The Spanish princess attended her first royal engagement without the oversight of her parents King Felipe VI and Queen Letizia on Wednesday, March 24. The 15-year-old royal presided over the 30th anniversary celebration of the Cervantes Institute, a language and cultural center in Madrid.
For the socially-distanced occasion, Leonor wore a long-sleeved, button-up dress and a pair of black heels, as well as a medical-grade mask.
In addition to meeting with the experts at the institute, the princess deposited two copies of the Spanish Constitution and Don Quixote de la Mancha in the institute's prized vault.
Coincidentally enough, Leonor's first engagement took place at the institute on her 13th birthday two years ago, when she read a portion of the same copy of the Spanish Constitution.
Additionally, she and her sister, 13-year-old Princess Sofia, read from the Don Quixote book in celebration of World Book Day last April.
This solo outing is just one of the many ways the princess is preparing for the day she ascends the thrown.
In September, Leonor will leave Spain to attend the UWC Atlantic College in Wales. The sixth-form college was attended by King Willem-Alexander of the Netherlands, as well as Crown Princess Elisabeth of Belgium.
According to a statement from the Spanish royal family, her parents will personally cover the cost of her attendance, which will set the king and queen back more than $90,000.
"Princess Leonor will reside, like the rest of the students, in the boarding school that the UWC Atlantic College has established within its campus," the statement added. "(She) will make this period of her education compatible with the progressive development of her institutional commitments in Spain."
Following Leonor's education at the two-year college, she will receive military training, as her father did when he was preparing to become the king of Spain.
