In 1191, Philippsthal had its first documentary mention in a
Schutzbrief ("protection letter") from
Pope Celestine III to the
Hersfeld Abbey. In this year, the Abbey founded a
Benedictine convent and named it after the living knightly family von Cruceburg, after whom the growing community of
Kreuzberg was then also named. The convent was destroyed in the
German Peasants' War in 1525 and forsaken by the nuns in 1568. All that is still preserved is the former convent church from the 12th century. On the spot where the convent stood, Landgrave
Philipp of Hesse-Philippsthal (b. 14 December 1655, d. 18 June 1721) had a palatial residence built in 1685, which he named
Schloss Philippsthal. By the late 18th century, this had become the local placename. After mining began at the Hattorf potash works in 1905, the craft and weaving village became an industrial community. During the time of Germany's division, the former Hoßfeld printing shop building earned some fame as the border between
East Germany and
West Germany ran straight through it. Only in 1976 did East and West Germany agree to a border adjustment that put the whole property in West Germany. ==Politics==
