Even before 1400 existed outside the city walls a so-called “Plague House” for lepers. After the enlargement of the city East direction and the associated expansion of its city walls the hospital relocated. After a brevis (papal summary) dating November11, 1245 by Pope Innocent IV (born in Genoa as Sinibaldo dei Fieschi, count of Lavagna) lepers should not be housed and had to live without priests nor church life, the single-storey house became a “Seelhaus” (house for souls) and served poor, passers-by, etc. as accommodation, to the existing buildings was a bathhouse added in 1425 and the buildings served as housing for poor old handicapped without family, thanks to the Ochsenfurt citizens who by “pious foundations for their souls salvation” gathered the necessary funds. With the approval of the cathedral chapter and “with God's help and pious peolple gifts and charity” in 1431 a hospital was built, i.e. the existing buildings converted. Early 16th century, after enlargement of the Church this hospital was demolished and re-built. This reconstruction was completed in 1551, it is mainly this building which has been preserved. The hospital itself had several possessions such as a “Hof” (farm and utility buildings) in Geißlingen and Euerhausen, two more of such near Geißlingen, and another one in Pfahlheim, the cathedral chapter had devised the Main-mill which already existed in 1397. The last prebendary moved out around 1890, the daily church service in the Kreuzkirche (also called Sacred Heart Church) was limited. Many decades the “Armen Schulschwestern” (School Sisters of Notre Dame) lived in the monastery buildings. They had a child repository, were active in the primary school and later led the Maria-Theresia kindergarten, at present the building is used by a number of clubs, on the first floor objects of the Heimatmuseum arekept. Eastern direction, located hidden behind the Church and the monastery is an enchanting “sleeping beauty”-garden with “stuck in the middle” a piece of city wall and a thick fortress Tower (which is very renovation-needy), in the long term a herbal garden à la Hildegard von Bingen or a biblical Garden may arise.
