Abstract: To monasteries and hospitals operating in the Middle Ages in Szczecin the most attention devoted German researchers in the pre-war period. Until the Reformation the city was a strong religious centre. In the 12th century at the St James’ church a Benedictine priory was founded, in the first half of the 13th century to the city arrived the Cistercian nuns and the Franciscans, about 100 years later the Carthusians, and the Carmelites in the 15th century. There were founded two hospitals - St George’s and St Gertrude’s which had their churches and chapels. To our times survived only a small number of early churches remains, a part of the archive materials is lost too.
