The Diocese of Samogitia was established when Samogitia officially converted to Catholicism in 1417. The seat of the diocese was in Varniai sometimes also known as Medininkai. The Varniai Priest Seminary was established only in 1623 by Bishop Stanisław Kiszka. Until 1743, the seminary shared premises with the Kražiai College. In 1770, a new brick building in the late Baroque style was built by Bishop. Motiejus Valančius, future bishop, began his studies at the seminary in 1822. From 1845 to 1850, he was the seminary's rector. When he became the bishop, Valančius organized a teetotalism movement, spent considerable effort on educating children and adults, and organised the smuggling and distribution of the banned Lithuanian books. Valančius lived in a wooden building next to the seminary and planted an avenue of poplar trees and established a garden with about twenty different species of fruit trees. After the failed anti-Tsarist Uprising of 1863, Tsarist authorities relocated the seminary to Kaunas. The former seminary building in Varniai was used as military barracks. In 1927–1931, the building housed the Varniai concentration camp. The new regime of President Antanas Smetona used the camp to house political prisoners, mainly members of the outlawed Communist Party of Lithuania. The building housed a secondary school in 1947–1961, and student dormitory and storage of a technical school in 1964–1984. Historical, archaeological, architectural studies of the building were carried out in 1984–1990. The bell tower and the original Baroque roof were reconstructed in 1991–1995 based on the original building depicted in a portrait of Jan Dominik Łopaciński. In 1999, the government of Lithuania and the Diocese of Telšiai established the Samogitian Diocese Museum. Over the years, the building suffered heavy damage and neglect, and requires extensive repairs. On 1 July 2015, the Samogitian Diocese Museum became a branch of the based in Telšiai.

The garden that was planted by Valančius is now known as Valančius garden and has a monument with his bust. The bust was removed by the authorities of the Lithuanian SSR in 1951. A local man hid the bust and it was reinstalled in its original location in 1990.
