In the autumn of 1825 the Emperor sailed to the south of Russia due to the increasing illness of his wife. During his trip he caught a cold which developed into typhus from which he died in the southern city of Taganrog on 19 November (O.S.)/ 1 December 1825. His wife died a few months later as the emperor's body was transported to Saint Petersburg for the funeral. He was interred at the Sts. Peter and Paul Cathedral of the Peter and Paul Fortress in Saint Petersburg on 13 March 1826.
