Foundation Around 612
Gallus, according to tradition, an
Irish monk and disciple and companion of Saint
Columbanus, established a hermitage on the site that would become the monastery. He lived in his cell until his death in 646, and was buried there in
Arbon (Canton of Thurgau). Afterwards, the people venerated him as a saint and prayed at his tomb for his
intercession in times of danger. They aided and taught virtue to the many pilgrims who came to St. Gall's tomb. 747 and the middle of the 8th century. A gentleman and judge of Thurgau, Waltraf (possibly, Waltram or Gaudran), in order to use the alms and collections that were being given at St. Gall's tomb to found a more regular monastery, attracted a local
Alemannic pastor
Otmar. During his abbacy the St. Gall School was founded.
Golden Age In the subsequent century, St. Gall came into conflict with the nearby
Bishopric of Constance which had recently acquired jurisdiction over the
Abbey of Reichenau on
Lake Constance. It was not until Emperor
Louis the Pious (ruled 814–840) confirmed in 813 the
imperial immediacy (
Reichsunmittelbarkeit) of the abbey, that this conflict ceased. By about 1353 the
guilds, headed by the cloth-weavers guild, gained control of the civic government. In 1415 the city bought its liberty from the
German king
Sigismund. A final attempt to expand the abbey resulted in the demolition of most of the medieval monastery. The new structures, including the cathedral by architect Peter Thumb (1681–1766), were designed in the late
Baroque style and constructed between 1755 and 1768. The large and ornate new abbey did not remain a monastery for very long. In 1798 the Prince-Abbot's secular power (the last to hold the title was
Pankraz Vorster) was suppressed, and the abbey was
secularized. The monks were driven out and moved into other abbeys. The abbey became a separate
See in 1846, with the abbey church as its cathedral and a portion of the monastic buildings for the
bishop. ==Cultural treasures==
