cultivated with medicinal plants and flowers. Trees and espaliers, visible in the 1744 representation, softened the mineral aspect of the place. The prior's house The prior's house, later known as the "Carthusian Priory", is a long building which was the southern end of the western façade of the church. The main part, which was wider, overlooked the courtyard of honour, which later became the "Carthusian courtyard". To the south, the building was extended by a narrower and probably more recent part, probably after 1744. The more qualitative treatment of the first part of the building was particularly evident in the façade, decorated with a pediment representing Mary of Magdala, at the entrance to a cave and with her hand resting on a skull. She is in fact considered by Christian historiography, and in particular by Cartusian historiography, as the first of the hermits, and as such enjoys great consideration in the order. The priory was vaulted by Odendal, who feared the risk of fire. The ground floor is arranged around a vestibule, on both sides of which the chapel and the "stove" were located. This vestibule leads to the cloister to the east, which is integrated into the building. In monastic times, the first floor of the prior's house was accessed by a spiral staircase between the church and the house. On the first floor, the prior's flat consists of four large rooms in a row overlooking the main courtyard and two rooms overlooking the courtyard. The second part of the building consists of a large vaulted cellar on the ground floor, topped on the first floor by three large rooms in a row with panelling and inlay. The largest of these has a stuccoed ceiling in the Rococo style. The furnishings in this part date from the mid-18th century. The kitchen wing actually comprised the kitchens on the ground floor and the brothers' rooms on the upper floor. This building, which was taken over during the monastic period, dates back to an earlier period. A Renaissance spiral staircase provides access to the upper floor. This earlier construction is also revealed by two fireplaces, which are attested to in 1673. In 1690, Prior Conrad Odendal had the water supply system in this building improved so that the friar cook had running water to preserve the fish. The hotel industry The construction of the guesthouse was planned to replace the "Böcklerhof",
