Reinhardsbrunn

Reinhardsbrunn in Friedrichroda near Gotha, in the German state of Thuringia, is the site of a formerly prominent Benedictine abbey, the house monastery of the Ludovingian Landgraves of Thuringia abbey extant between 1085 and 1525. Later used as an administrative seat by the Ernestine dukes of Saxony, the property was turned into a castle and park erected by the Dukes of Saxe-Coburg and Gotha from 1827.
