Santa Maria dell'Anima is one of the many medieval charity institutions built for pilgrims in Rome. The church found its origin in 1350, when Johannes (Jan) and Katharina Peters of Dordrecht bought three houses and turned it into a private hospice for pilgrims, at the occasion of the Jubilee of 1350. Jan Peters may have been a Dutch merchant or papal soldier; Dordrecht belonged to a region which later became independent as the Netherlands. They named the hospice "Beatae Mariae Animarum" ("Blessed Mary's of the Souls"). It was erected on its present site in 1386. In the 15th century Santa Maria dell'Anima expanded to be a hostel for visitors from the entire Holy Roman Empire, though initially the occupants were primarily from the Low Countries and (from the middle 15th century) the Rhineland.
