After Henri's death on 24 August 1883, Maria Theresa and a minority of Henri's supporters held that Juan, Count of Montizón, as senior male descendant of Louis XIV, was his successor. Juan's wife was Maria Theresa's sister, Maria Beatrix.[citation needed]
Maria Theresa was instrumental in building a crypt for the French Royal Family at the Church of the Annunciation of Our Lady on Castagnevizza in Görz (now in Nova Gorica, Slovenia).[2] It was her wish that the last of the Bourbons be gathered in one place together within the monastery at Castagnevizza.[2] Three years after the death of her husband Henri, Maria Theresa died on 25 March 1886 in Görz and was interred with her husband in the crypt of the church of Franciscan Monastery of Castagnevizza in Görz.
