Two hillforts are located in the vicinity of the Molavėnai village. Two nature monuments are protected by the state – an old oak tree near one of the hillfots and a stone called Mokas. Molavėnų I hillfort was first erected in the 1st century AD and consisted of defensive fortifications and a wooden fort. The site is located on a long (350 m), narrow projection into a bend of the river Šešuvis. The site is protected on the northeast and southwest by steep slopes, marshy banks, and the river. To protect it on the northwest, the only known Lithuanian double defensive system that uses earth and wooden outworks was erected on the projection’s neck. In all, it consisted of five ditches, four earthworks, and three levelled courtyards. A fortified settlement was built at the southeast end. In addition, the levelled hilltop areas were surrounded by palisades of sharpened poles. Artefacts dating from the early 1st century to the early second millennium were found during 21st century excavations. The site was eventually abandoned due to continued erosion and the shrinking hilltop.
Molavėnų II hillfort was built 400 m upstream in the 12th century on another projection at the confluence of the river Šešuvis and its tributary, the Jaujupis. Only the northeast and east sides were not protected by natural defences and so were instead guarded by a series of four earthworks and four ditches. A 20 m long earthwork with a corresponding ditch was constructed on the southwest slope. The flat hilltop was ringed by a wooden defensive wall. A tower was erected on the big earthwork, and wooden palisades on the other earthworks. A 2009 excavation discovered pottery dating to the 12th–14th centuries. Dry stone revetting was also found in one ditch.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
