Treuenstein Castle

Located in the borough of Gries, it was built between 1276 and 1278 by Meinhard, Count of Tyrol for his trusted vassal Friedrich, a burgher from Bolzano.

His loyalty impressed Meinhard so much that he chose to buy an estate located near the Fagen creek near the entrance of the Sarntal valley from the Walbensteiner family in 1276.

[1] The newly built castle was given the name Treuenstein (Trewenstain), meaning loyal stone in German, by Meinhard to emphasize his complete trust in his vassal.

[2] Friedrich von Treuenstein's impressive career continued unabated: in 1286 or 1287 Count Meinhard nominated him capitaneus et rector Tridenti (captain and administrator of Trent) before he died around 1294.

[6] In 1656 the nobleman Cyriac Troyer von Giessbach acquired the ruins of the castle and the nearby manor, renaming it Troyenstein.
