More than 50 years ago, the nuns of the holy Karl Borromäus made a new start in the former Benedictine abbey Grafschaft, which was founded in 1072, after their expulsion from Silesia. The beautiful baroque building, which was erected in the first half of the 18th century, was in a deplorable condition. After the Benedictine monks were forced to move out in 1804 as a result of the secularisation, the building had been used for the most varied purposes and had suffered even more damages in 1945 in the last few days of the war. The first three nuns came to Grafschaft in February 1948. They set to work themselves in order to first ensure that they had some accommodation. The nuns, who were scattered over the whole of the federal territory through expulsion from Silesia, successively came together in the present mother house of Kloster Grafschaft. Through their own hard work, with very modest funds and under great difficulties, they tried to prepare the house so that sick people could be admitted. On 24 April 1950, Cardinal Dr. Lorenz Jäger of Paderborn inaugurated the reestablished mother house of the merciful nuns of the holy Karl Borromäus, and on the 1 July of the same year, it was possible to open the hospital in part of the building.
