Queen Sofía of Spain is in the midst of an international tour. As she travels to different cities representing her nation of Spain, the Queen has carried herself and her institution with elegance, creating the space for tributes that pay a subtle homage to her late sister, Princess Irene.

The Queen traveled to the Universidad CEU San Pablo in Madrid to preside over the inauguration of the congress "La Monarquía Española y la Independencia de los Estados Unidos. 250º Aniversario," held in the university's Aula Magna. Sofia attened as President of the Honor Committee, a role that reflects her institutional standing and personal investment in the shared history between Spain and the United States. The two-day event united leading national and international historians to examine Spain's political, military, and cultural contribution to American independence.

It is the latest stop in a commemorative journey that has taken the Queen across the Atlantic. Earlier this year, she represented her country in Miami at the launch of the America&Spain250 initiative, and last October, she was in Washington.

Doña Sofía's Most Treasured Jewel

In her most recent outing, the Queen wore a delicate jewel that is imbued with personal meaning; she wore a pearl and stone necklace on a golden chain. It's an understated piece she has worn on many occasions, including outings alongside her late sister, Princess Irene.

Ever since her sister's death in January, Queen Sofía has worn items that can be interpreted as tributes to the Greek princess. "Their Majesties the King and Queen, and Her Majesty Queen Doña Sofía, regret to announce the passing of Her Royal Highness Princess Irene of Greece," read the official royal statement that was shared at the time.

A Lifelong Bond

Sofia and Irene were best friends throughout their lives, sharing a passion for many things, including archaeology. The two were involved in excavations in the Decelea region, where they spent much of their youth. They co-wrote two books about their findings and research in the 1960s and continued to make time for eachother throughout their lives despite their busy schedules and lives.

Irene's death was a particularly significant loss for Queen Sofía, who lost her sister and their cousin and close friend, Tatiana Radziwill, within weeks of each other.
