Telšiai Bernardine monastery and seminary complex – is one of the most important sacred buildings in Samogitia, Lithuania.

The complex comprises the Bernardine monastery and church (which in 1926 became a cathedral), the seminary, the Episcopal palace, school and other buildings.

The church was restored on two occasions in 1897–1898, when a metal gallery surrounding the whole second floor with lanterns was erected, and historic style masonry churchyard gates were built.

On 4 April 1926, Pope Pius XI issued an apostolic constitution “Lituanorum gente“ which established the Lithuanian church province and Telšiai diocese.

Justinas Staugaitis (1866-1943), a prominent church and Lithuanian government figure, was chosen as the first bishop of Telšiai.

On 5 February 1946 he was arrested by the officials of the Soviet government, tortured and executed in Vilnius on 18 November 1946.
