The National Day of Andorra, also known as Our Lady of Meritxell Day, is one of the most significant holidays in this small European nation. Celebrated annually on September 8th, this day is dedicated to the patron saint of Andorra, Our Lady of Meritxell. While it is a religious holiday with a deep catholic significance, it is also a cultural event that shows the spirit and heritage of Andorra.

The holiday is named after the small chapel in Meritxell, Andorra, where a statue of the Virgin Mary was said to have been found under miraculous circumstances. The story tells of a wild rose bush found blooming in the dead of winter, with the statue tucked beneath it, which was interpreted as a sign from heaven. Ever since, the same spot has been a place of pilgrimage for the faithful and tourists alike.

During the National Day, the entire country becomes festooned with decorations and the air is filled with joy and celebration. There are processions, masses, and cultural events taking place throughout the country, all of which the people take pride in. It's a day where Andorrans, regardless of their age, let go of everyday concerns to give themselves wholeheartedly to the tradition and festivity of the national celebration. From the hauntingly beautiful hymns sung at the Lady of Meritxell Sanctuary, to the festive dances and parades in the streets of Andorra's towns, this day truly showcases the vibrant culture of this country.
