List of Jesuit sites
This list includes past and present buildings, facilities and institutions associated with the Society of Jesus. In each country, sites are listed in chronological order of start of Jesuit association. Nearly all these sites have been managed or maintained by Jesuits at some point of time since the Society's founding in the 16th century, with indication of the relevant period in parentheses; the few exceptions are sites associated with particularly significant episodes of Jesuit history, such as the Martyrium of Saint Denis in Paris, site of the original Jesuit vow on . The Jesuits have built  many new colleges and churches over the centuries, for which the start date indicated is generally the start of the project (e.g. invitation or grant from a local ruler) rather than the opening of the institution which often happened several years later. The Jesuits also occasionally took over a pre-existing institution and/or building, for example a number of medieval abbeys in the Holy Roman Empire. In the third quarter of the 18th century, the suppression of the Society of Jesus abruptly terminated the Jesuit presence in nearly all facilities that existed at the time. Many of these, however, continued  their educational mission under different management; in cases where they moved to different premises from the ones operated by the Jesuits, the Jesuit site is mentioned in the list as precursor to the later institution. Outside Rome, sites operated by Jesuits since the early 19th century are generally different from those before the 18th-century suppression. Later episodes of expulsion of the Jesuits also terminated their involvement in a number of institutions, e.g. in Russia in 1820, parts of Italy at several times during the 19th century, Switzerland in 1847, Germany in 1872, Portugal in 1910, China after 1949, Cuba  in 1961, or Haiti in 1964. The territorial allocation across countries uses contemporary boundaries, which often differ from historical ones. An exception is made for Rome which is highlighted at the start. Similarly and for simplicity, only modern place names are mentioned, spelled as on their main Wikipedia page in English, even in cases where those modern names were never in use during the time of local Jesuit involvement.
