The grandson of Spain’s wealthiest woman has tied the knot today in a move that will see two of the country’s richest families merge as one.
Carlos Fitz-James Stuart y Solís, the Count of Osorno, wed his fiancee Belén Corsini in a glamorous ceremony at Liria Palace, in Madrid this afternoon.
Their union sees two of Spain’s wealthiest families, the Albas and the Corsinis, join together til’ death do them part.
Belén is the great-granddaughter of Carlos Corsini Senespleda, engineer and founder of the construction and public works company Corsan, which was sold for 325 million euros in 2004.
The Count is the youngest son of the 19th Duke of Alba, who inherited an estimated £2.2billion worth after the late Duchess of Alba passed away in November 2014.
Spanish socialites, celebrities and other high profile individuals all turned out for the couple’s big day, which was only publicly announced last September.
The event marked the biggest society wedding of the last 18 months after scores of aristocrats across Europe were forced to put plans for their lavish nuptials on hold due to the pandemic.

The newly wed couple were joined in holy matrimony today after three years of dating, and announcing their plans back in September.
Spain’s looser Covid-19 restrictions meant up to 300 guests could dance the afternoon away at today’s indoor ceremony, with up to eight people per table.
A handful of Spain’s biggest names flocked to the must-see event, including the Count’s older brother Fernando Fitz-James Stuart and his wife Sofia Palazuelo, who wed in 2018.
When the Duke of Huéscar married Ms Palazuelo at the same estate in 2018, there were 750 guests including Queen Sofia of Spain.
Hundreds of people lined the streets and took pictures of those arriving, including the Duke’s niece, Brianda Fitz-James Stuart.
Belen’s family were also in attendance, with Alejandra Corsini and Alejandro Munoz celebrating the family affair in the Spanish capital.
The event marked the biggest society wedding of the last 18 months, after the Covid-19 pandemic crippled socialites’ plans for lavish ceremonies across Europe.
The newly wed couple spent lockdown at the family’s 18th century estate Liria Palace in Madrid, with the Count’s father and uncle.
Belén, who manages family businesses, is the granddaughter of Jacobo Corsini Marquina and the daughter of Juan Carlos Corsini and Mónica de Lacalle Rubio.
The Corsini Muñoz family are descendants of the engineer Carlos Corsini Senespleda, founder of the company Corsán construction company.
Belén then is a descendant of one of Spain’s most valuable companies of the last century.

The couple’s union became the first family wedding since 2018, when Carlos’ elder brother Don Fernando Juan Fitz-James-Stuart y Solís-Beaumont, to use his full name, tied the knot with girlfriend Sofía Palazuelo in a lavish ceremony at his family home.
Following the ceremony the newly weds hosted an aperitivo and long lunch on the same estate serving beer from the family’s own brewery La Casa de Alba.
They performed their first dance to a waltz before their guests joined them on the dance floor and partied until the early hours.
It is no surprise that the wedding was a lavish affair with the groom being the grandson of the late Duchess of Alba, or María del Rosario Cayetana Alfonsa Victoria Eugenia Francisca Fitz-James Stuart y de Silva, to give her the full name.

The Count of Osorno came into serious wealth after the death of his grandmother, María del Rosario Cayetana Alfonsa Victoria Eugenia Francisca Fitz-James Stuart y de Silva , seven years ago.
Worth an estimated £2.2billion, the Spanish duchess was one of Europe’s wealthiest aristocrats when she passed away in November 2014 at her Seville residence, Duenas Palace.
Friends, relatives and well-wishers paid their respects to the duchess, also known as ‘Cayetana’, after she died following a battle with pneumonia.
Her husband Alfonso Diez, who was 24 years her junior, is thought not to have received any of her fortune, which included an impressive property portfolio, 50,000 pieces of artwork and 18,000 rare books, after he signed a document renouncing any claim to her wealth prior to their marriage in October 2011.
Instead, the Duchess – who is a direct royal descent from King James II of England – left her entire estate to her six children, with them each receiving a palace, as well as thousands of acres of land. Her eight grandchildren are also said to have inherited a substantial chunk of her estate.
A relative of Winston Churchill, the duchess shared toys with England’s future Queen Elizabeth while living in England as a girl.
