They maybe also built the Hospital of the Knights of St. John; excavations in 2009 and 2010 revealed foundations of this ancient building. When the Templar preceptory was decreasing, the Hospital was increasing in power and wealth (starting from the 14th century). The building must have had a hall for the care of pilgrims and ill people. This hall should be built in the 13th century. From about 1330 on, the archives of the Hospital are preserved, and tell us the further history of the complex. In 1523, two Sisters in the Third Order of St. Francis started renovating the building, after it was abandoned by the Knights of St. John. In the year 1540, it was officially declared "Monastery" by Charles V.
