Vincens Lunge. A hospital run by the nuns at Nonneseter Abbey was first documented in 1411. It seems probable that this was the forerunner of St. Jørgen's Hospital (Sankt Jørgens Hospital) which was later associated with the research and treatment of leprosy by Daniel Cornelius Danielssen. Site and buildings The abbey was located on a promontory on the north bank of the Lillestrømmen, a stream which once connected two bodies of water, Store Lungegårdsvannet and Lille Lungegårdsvannet, approximately in the area of the present Kaigaten. The surviving buildings were mostly destroyed by a fire in 1891, and of the monastic buildings there remains nothing to be seen. Of the abbey church there survived the base of the west tower and the Nonneseter Chapel, originally the south chapel off the choir, which after the fire were acquired in 1891 by the Society for the Preservation of Ancient Norwegian Monuments. The single storey remaining of the west tower, the Tårnfoten ("tower foot"), measures 8.6 metres square. It was originally clad with dressed stone. In the west wall is a portal with a round arch, and in the east wall another, which would have connected to the body of the church. It is now used as a memorial chapel to the fallen of World War II. The Romanesque tower foot is more old-fashioned in style than the body of the main church apparently was, indicating the possibility that it could have belonged to an older structure predating the arrival of the Cistercians with their characteristic building style. The church lay to the east of the tower. The original building was quite small, but seems to have been extended eastwards in the later 13th century with a new choir and choir chapels; it had a single aisle. The graveyard was to the north of the church, and the monastic buildings to the south, but there are too few remains of them to establish the exact layout. The site was archaeologically excavated in 1872 and again in 1892. Nonneseter Chapel The Nonneseter Chapel (Nonneseter kapell) at Kaigaten 3 is believed to have been one of the choir chapels. It measures about 8 metres by 7 metres, and contains a vaulted ceiling and Gothic arched windows. It dates from around 1250, which seems to be when the church was extended. Between 1951 and 1989 it was used as a church for deaf persons. It is now
