In Monaco-Ville, the Palais Princier de Monaco has announced that Their Serene Highnesses Prince Albert II and Princess Charlene of Monaco will undertake an official visit to the Kingdom of Spain from June 1st through June 2nd, 2026.

The visit will commemorate the 150th anniversary of diplomatic relations between the Principality of Monaco and the Kingdom of Spain, as well as the 10th anniversary of the Spanish branch of the Fondation Prince Albert II de Monaco.

Relations between the Principality of Monaco and the Kingdom of Spain date to the early 16th century. In 1524, the Treaty of Burgos, signed by Honoré I of Monaco and Emperor Charles V, placed the Principality under Spanish protection and established a period of close political and dynastic relations between the Grimaldi dynasty and the Crown of Spain that endured for centuries through diplomatic, cultural, and royal exchanges.

According to the Palais Princier, the Sovereign Prince will hold a meeting with His Majesty King Felipe VI of Spain at the Palacio de La Zarzuela. In the afternoon, Their Majesties King Felipe VI and Queen Letizia of Spain will host a luncheon in honour of the Sovereign Prince Couple at the Palacio de La Zarzuela on the occasion of the official visit.

The Sovereign Prince will also hold a meeting with the Prime Minister of Spain, Pedro Sánchez Pérez-Castejón, during the visit.

On June 1st, Prince Albert II and Princess Charlene will preside over the inauguration of the exhibition Monaco y España: Cinco Siglos de Historia Compartida at the Real Jardín Botánico de Madrid.

The exhibition, dedicated to five centuries of historical relations between Monaco and Spain, forms part of the broader commemorations marking the anniversary year and is expected to examine the dynastic, diplomatic, and cultural ties between the Principality and the Crown of Spain across several centuries.
