developed a fever two days before giving birth. On 8 March 1801, early in the morning a daughter was born after prolonged labour, but she was reportedly 'very weak' and died within the day, possibly the hour. According to Joseph's biographer Domanovszky, the child was called Alexandra, but Hankó and Kiszely, who exhumed and examined the bodies of the infant, state that she was registered as Paulina in her death certificate and had no separate entry in the baptism registry of the , thus was probably christened after her death. Her casket was inscribed with the same name. She was buried in the Capuchin church in the presence of many Hungarian dignitaries. In 1838, she was transferred to the Palatinal Crypt with the urns containing the intestines and heart of her mother. A later investigation determined that the remains were those of a fully and normally developed newborn, not at all 'very weak', and thus concluded that she probably died of hypoxia during the long delivery. The death of the baby devastated both parents, but at first it seemed like Alexandra would recover. Despite being treated by four excellent doctors, her condition did not improve, and the breast milk she could not nurse with apparently worsened the fever. From 12 March, she was treated against typhoid fever, and early on the 15th, she became delirious, dying on 16 March. Emperor-King Francis ordered a mourning period of six weeks for the court, with some modifications because of the late archduchess' different religion. The embalmed body was laid on an ornate catafalque in the Russian Orthodox chapel built for Alexandra's personal use. It lay in state for three days before being placed in a separate building in the garden for six weeks as Orthodox customs commanded. Alexandra was buried on 12 May at noon in the Capuchin Church, her clothes were remade for clerical usage and Joseph gifted her mineral collection the Royal University of Pest eight years later. On 17 March, Joseph went to Vienna, then travelled around Italy. When he returned in the spring of 1802, he started the construction of the in Üröm, where Alexandra had requested to rest. She was reburied there in 1803, and, after multiple exhumations and disturbances, is there as of 2022. After a grave robbery in the late 1980s, an investigation was carried out, determining that Alexandra Pavlovna suffered and probably died of tuberculosis.
