The exact date of the creation of the castle is unknown, later sources only give a not very sure year 1284. In historical documents the castle appeared only in 1429, although its architectural form allows us to assume that the stone fortifications in place of earlier wood and earth ramparts could have been created in the mid-fourteenth century, and even at the end of the thirteenth century. The castle was one of several strongholds constituting the economic base of the commandry of Wenden. Due to not too much importance, it did not appear too often in the sources. Like most of the Livonian castles, Trikaten was destroyed by the army of Ivan the Terrible in the second half of the 16th century. After a short reign of the Polish–Lithuanian Commonwealth, it was occupied by the Swedes and finally destroyed during the war with Russia at the beginning of the 18th century.
The stronghold consisted of an outer bailey and an upper castle separated from it by a moat. East and north-west wing of upper castle had buildings. The main element of the castle defense was the main tower located in the north-east corner of the upper castle, next to the gate leading to the bailey. An additional, external protection was provided by the nearby river from the east, west and south.
Only a few and a dozen meters long fragments of defensive walls and a part of the base of the tower have survived to the present. Currently, the castle area has a park and a small stage where cultural events are organized.
