Jews lived in Feldkirch in the first half of the 14th century in a place occupied today by the district of Heiligenkreuz outside the city walls. A lawsuit from 1343 between Count Albrecht I von Werdenberg, ruler of Bludenz, and Count Ulrich I of Montfort, ruler of Feldkirch, dealt with seven Jewish families who moved from Feldkirch to Bludenz, and it was decided that they belonged to the count of Montfort. It is unknown whether the families returned to Feldkirch.
In 1349, during the plague, the Jews of Feldkirch were accused of poisoning wells and were burnt at the stake. In 1443 the Jews of Feldkirch and Konstanz were arrested due to a blood libel; the Jews of Konstanz were released after five years, but the fate of the Jews of Feldkirch is unknown.
