Havránok

It is on a hill above the Liptovská Mara water reservoir around 2 km (1.2 mi) from the village of Bobrovník, about halfway between Ružomberok and Liptovský Mikuláš in the Liptov region.

The archaeologists unearthed a prehistoric Celtic hill fort and a medieval wooden castle in the 1960s, during the construction of the Liptovská Mara dam.

During the Iron Age and the Roman Era, the shrine of Havránok was an important religious center of the Celts living in Slovakia.

The prosperous oppidum was destroyed along with other Celtic settlements in Slovakia around the beginning of the Common Era either by the Germanic tribe of Quadi or by Dacians.

The shrine also included a number of smaller wooden columns, with burnt offerings (mostly jewels, agricultural products, and animals) buried next to them.
