The symbol of the Jesuits

Initially, several residential buildings, churches, a Dominican monastery, and gardens were built on the territory of Clementinum in the Czech Republic. In the middle of the 16th century, the Jesuit College was founded, three years later (1555) the entire territory of the complex passed to the Jesuits. Gradually they expanded their possessions – they built a school, a printing house, a theater in Clementinum, the university also passed into their full control.

Good to know! In the 17th century, the Jesuit College became the largest Jesuit training center in the world.

At the end of the 18th century, the Jesuit order was expelled from the Czech Republic, because according to the king, the influence of the order on society became too serious. Since then, Clementinum has become a secular institution. Later in Clementinum they began to collect and store books from Charles University, as well as libraries of collegiums and Jesuit temples.
