In 1956 and 1957, the hospital foundation acquired some buildings right near the hospital that were on the Rhine and on Niederstadtstraße, and in the years that followed, until 1962, the hospital was thoroughly renovated and also expanded. The expansion claimed the "Hospitalsgasse" ("Hospital Lane") as a victim; this no longer exists. The gynaecology department was housed in the new building on the Rhine and new operating rooms were built on the main floor at the old building. Moreover, the hospital acquired new two- and three-bed rooms. A further expansion building was begun in 1975 and dedicated two years later. Since then, it has been used as a nursing home for seniors.
