The article presents the history and accomplishments of Jesuit architecture in the Polish-Lithuanian Commonwealth from the late sixteenth to the late eighteenth century. The author sees Jesuit architecture as a distinct and homogeneous element within Polish architecture. The paper starts with a brief presentation of the existing research in the subject. It moves on to enumerate the activities of the Society in the field of construction, divided into three major booms: the first roughly between 1575 and 1650, the second between 1670 and 1700, and the third from 1740 to 1770, divided by periods of relative decline caused by a succession of devastating wars. The paper identifies the most important architects involved in the construction of Jesuit churches, as well as their most notable works. The paper ends with a brief note concerning the fate of the Jesuit churches after the suppression of the Society and the partitions of Poland.
