The de Grienenech family first appears in the historical record in 1260, but it is unclear whether they had any ties to the castle.

The first time the castle is clearly named in a record is in 1515, when it was owned by St. Nicolai monastery in Chur and may have already been a ruin.

[1] In 1811 and again in 1904 several large Carolingian coin hoards were discovered during construction of the Ruschein road near the castle.

[2] One of the containers that held the coins, which is made from antler and T-shaped, is now kept in the British Museum.

The tower is an uneven pentagon shape with only the west and south-west wall still standing.
