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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
