Havránok is an important archaeological site in northern Slovakia. It is located on a hill above the Liptovská Mara water. The archaeologists unearthed a prehistoric Celtic hill fort and a medieval wooden castle in the 1960s, during the construction of the Liptovská Mara dam. Both objects have been partially reconstructed. During the Iron Age and the Roman Era, the shrine of Havránok was an important religious center of the Celts living in Slovakia.
The Havránok hill fort was an important religious, economic, and political center of the Púchov culture (300 BCE - 180 CE), in which the dominant Celtic tribe of Cotini mingled with the older people of the Lusatian culture. 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.
A medieval wooden castle existed near the remnants of the ancient hill fort from the 11th to 15th century CE.
The hill fort was a religious center of the Celts living in northern Slovakia. Its wooden shrine was built in the 1st century BCE around an exceptionally high wooden column, probably a totem or a statue. Excavation of a ritual pit situated near this central cult object revealed bones of at least seven people sacrificed during druidic rituals. The victims were beaten to death, quartered, and in some cases also burnt. Parts of their bodies were subsequently thrown into the pit. A large number of agricultural tools in the vicinity of the pit indicate that human sacrifices may have served to insure a good harvest.
The shrine also included a number of smaller wooden columns, with burnt offerings (mostly jewels, agricultural products, and animals) buried next to them.
In addition to the shrine, the reconstructed buildings include a fortified gateway of the hill fort with a part of the stone walls (120-50 BCE), farmstead (300-100 BCE), a pottery kiln (300-100 BCE), and huts from various periods.
In the Iron Age and the Roman Era, Havránok was surrounded by several Celtic villages. Some of them were inundated by Liptovská Mara reservoir. The small medieval castle is also partially reconstructed and the whole area of Havránok is now an open air museum. The site was proclaimed the national cultural monument in 1967.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
