One of the most influential Catholic orders that contributed in an important degree to development and spreading of Marian devotion was the Society of Jesus. Aside of their educational and pastora! activities, the Jesuits served as custodians of important Marian pilgrimage sites, as was also the case of the residence in Golčův Jeníkov, where they remained in the years 1657-1773.

The everyday life of the residence brought about many activities, among them the organization of festivals along the lines of Baroque ostentatiousness and regular radius of pilgrimages.
