Rhäzüns Castle above the Hinterrhein

Rhäzüns Castle (Chastè da Razén in Rhaeto-Romanic)
It is not known when the plant or its predecessors were built. A castle probably existed on the site of today's palace as early as the 10th century; A castellum Beneduces et Rezunnes is mentioned in documents of Emperor Otto I and Otto II in the years 960 and 976.
The first proven representative of the barons of Rhäzüns was Arnoldus de Ruzunne, who is mentioned in 1137/39 in the Gamertinger documents. The first documented mention of Rhäzüns Castle itself appears in a sales deed from the Disentis monastery from the year 1282. After the death of the last Rhäzünser Georg in 1459, a long succession dispute arose between the Counts of Hohenzollern-Hechingen von Zollern and the Werdenbergers. In 1461 the castle fell to the Zollern family by arbitral award, who pledged it to Conradin von Marmels in 1437. It came into the possession of Maximilian I in 1497 through an exchange for the Haigerloch estate.
After the death of Hans von Marmels in 1553, Rhäzüns changed hands several times until 1695. Bartholomäus von Stampa and in 1558 Johannes von Planta followed as pledge holders.
In 1695 Austria took over the rule and had it administered by officials. This prevented the Rhäzün rule from being integrated into the politics of the Three Leagues. On December 29, 1809, the rule of Austria passed to France. After the collapse of the Napoleonic Empire, Rhäzüns was initially returned to Austria in 1814 and was added to the canton of Graubünden in 1815 at the Congress of Vienna.
It was bought by the last Habsburg administrator, the doctor and magistrate Georg Anton Vieli. It remained in his family's possession until 1927. In the early 1850s, Father Theodosius Florentini set up a girls' school there, which was moved to Rorschach in 1854. After the lessee of the estate had lived in it, the castle stood empty and began to fall into ruin.
On December 11, 1926, it was bought and extensively renovated by the «Non-profit cooperative for Swiss abroad holiday home Rhäzüns».
