According to Luxarazzi:
The Grand Duchess offered the flowers she received upon her arrival as a gift to the statue of Our Lady of Fátima.
The shrine of Our Lady of Fátima above Wiltz was set up…by a group of local parishioners, who, having taken refuge in a cave during the Battle of the Ardennes in the winter of 1944-45, promised to erect a sanctuary after the war if they survived unharmed.
…people of Portuguese ancestry…make up an estimated 120,000 of the 550,000 people living in the Grand Duchy.
