Rauna Castle ruins was the principal residence of the Archbishopric of Riga in which at for certain period each year it was visited the Archbishop with his entourage. The first mention of Rauna Castle date back to 1381, although historians agree that it may have been built here even earlier. 18th century sources mention the castle as being erected in 1262, following a proposal of Albert Suerbeer, Archbishop of Riga. It is noted that the castle was one of the most important centres of the archdiocese.
The biggest reconstructions occurred under the reign of Archbishop Jasper Linde. One of the new towers built was named Garais Kaspars (Tall Jasper), after the archbishop, and a small settlement developed around the castle, which later became the village of Rauna.
The devastation of the castle started in 1556 with attacks by the Livonian Order, which lasted until the end of the Livonian War. The worst damage to the castle occurred from 1657 to 1658, during the Second Northern War between the Polish–Lithuanian Commonwealth and the Swedish Empire. The castle was deserted after that and slowly turned to ruins. In 1683 the king of Sweden ordered the destruction of anything that resembled a fortress around the castle, so all towers were demolished. Today the Rauna Castle ruins are preserved. Many walls and even the bases of the towers remain.

It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
