She is the daughter of Prince Nikolaus and Princess Margaretha of Lichtenstein, sister of Grand Duke Henri.
The couple got married in a religious ceremony in the Schottenkirche in Vienna. Princess Maria Anunciata and her partner Emanuele Musini already married in a civil ceremony in Italy a couple of weeks ago.
Grand Duke Henri and all of his siblings were present at the ceremony in Vienna: Archduchess Marie Astrid and her husband Archduke Carl Christian of Austria, Prince Jean of Luxembourg and his wife Countess Diane of Nassau, as well as Prince Guillaume and his wife Princess Sibilla of Luxembourg.
Hereditary Grand Duke Guillaume and his wife Hereditary Grand Duchess Stéphanie were also present. They were further accompanied by Prince Félix and his wife Princess Claire, Prince Louis and his fiancée Scarlett-Lauren Sirgue, as well as Princess Alexandra and Prince Sébastien.
Belgian King Philippe and Queen Mathilde had to cancel their trip to Vienna on short notice, as they had to quarantine due to a positive Covid-19 infection.
