Wenzeslaus of Thun

Wenzeslaus of Thun (13 August 1629 – 6 January 1673) was a Czech clergyman and bishop for the Roman Catholic Diocese of Passau.

He was the son of Count Johann Sigismund of Thun und Hohenstein and his second wife Anna Margareta of Wolkenstein.

He was the half-brother of the two Salzburg prince-archbishops Guidobald and Johann Ernst von Thun und Hohenstein.

Just two years after the city fire, the only 35-year-old Wenzeslaus, who had previously been a canon in Salzburg and a capitular in Passau, was elected on 27 March 1664 to succeed Karl Joseph of Austria and thus become the new prince-bishop.

He dedicated his reign as Prince Bishop of Passau to the reconstruction of the cathedral and the repair of the damage caused by the Thirty Years' War.
