Monarchic symbol par excellence, the crown also represents the Grand Ducal dynasty and the head of State, Grand Duke Henri. This is why official symbols such as flags or medals typically feature a crown-wearing letter H. Grand Duke Henri acceded to the throne with the abdication of his father Grand Duke Jean in the year 2000 and then named his eldest son Guillaume as Hereditary Grand Duke, ensuring shared responsibilities and continuity to the country's dynasty. The Grand Ducal family actively participates in social and cultural activities across the country, placing themselves in the royal tradition while embracing the country's 21st century modernity. Grand Duke Henri, his wife Grand Duchess Maria Teresa and their five children are official patrons to numerous national associations and causes in the fields of humanitarian action, sports, art or music. They also represent the country on trade missions and during state visits to foreign countries. The Grand Ducal Family shares a very special bond with the population. On the eve of the National holiday for instance, the entire family traditionally walks from the Grand Ducal Palace to the 'Gëlle Fra' and admires the fireworks, together with countless spectators.
