970-metre-long prehistoric megastructure found submerged in Baltic Sea

Published

on

Geologists have discovered a 970-metre-long megastructure of linear arranged stones, located at a depth of 21 metres on the seabed of Mecklenburg Bight in the Baltic Sea.

The megastructure consists of approximately 1,500 stones and large boulders, which was constructed around 11,000-years-ago during the early Mesolithic period.

According to a study published in the Proceedings of the National Academy of Sciences (PNAS), the megastructure was built by Stone Age hunter-gatherers for hunting herds of the Eurasian reindeer (Rangifer tarandus), which migrated seasonally through the sparsely vegetated post-glacial landscape.

Similar constructions, which are known as drive lanes, are used for manipulating the movement direction of the animals so that they can be easily trapped in a bottleneck and killed. In the example at Mecklenburg Bight, this bottleneck would be between the  adjacent lakeshore and the wall, or even into the lake.

Marcel Bradtmöller from the University of Rostock, said: Excluding natural processes and a modern origin, the stonewall could only have been formed after the end of the last ice age, when the landscape was not yet flooded by the Baltic Sea.”

“At this time, the entire population across northern Europe was likely below 5,000 people. One of their main food sources were herds of reindeer, which migrated seasonally through the sparsely vegetated post-glacial landscape,” added Bradtmöller.

According to the researchers, the discovery holds immense scientific significance, being not only the oldest known human structure found in the Baltic Sea, but also for providing new insights into the subsistence patterns of early hunter-gatherer communities.

A further study of the stonewall and the seabed will involve using side-scan sonar, sediment echo sounder, and multibeam echo sounder devices. In addition, underwater archaeologists from the University of Rostock and archaeologists from the LAKD M-V, are scheduled to explore the stonewall and its environs in search of archaeological artefacts that could aid in further understanding the structure’s significance.

Archaeologists find Roman villa with ornate indoor plunge pool

Published

By

Archaeologists from the National Institute of Cultural Heritage have uncovered a Roman villa with an indoor plunge pool during excavations at the port city of Durrës, Albania.

During antiquity, Durrës was founded by Ancient Greek colonists from Corinth and Corcyra.

The colony emerged into a major trading centre, which during the Roman period was annexed into the expanding territory of the Roman Republic following the conclusion of the Illyrian Wars.

By the 4th century, the city (named Dyrrachium), emerged as the capital of the Roman province of Epirus nova, covering the region of Ancient Epirus.

Archaeologists excavating a former residential part of the ancient city have uncovered a high status Roman villa that dates from between the 1st and 4th century AD.

The villa interior contains an indoor pool, richly decorated with frescoes on the walls and mosaic flooring with tiles and inlays of marble, stone, glass and ceramics. Located adjacent to the pool are shallow square basins lined with waterproof mortar, believed to be the remains of an ancient water feature.

Within the northern area of the excavation site, archaeologists found a large brick floor from a thermae, a Roman bath, and further traces of walls from the wider complex.

In the western area, the team discovered fragments of relief stucco that was used to decorate the walls and ceilings of the villa. The reliefs depict anthropomorphic and floral motifs, further indicating the wealth of the villa inhabitants.

According to the archaeologists, the villa was destroyed by an earthquake in the 4th century, corresponding with ancient sources that describe a powerful earthquake causing buildings to collapse and the city defences to crumble.

Archaeologists excavate medieval timber hall

Published

By

Archaeologists from the University of York have returned to Skipsea in East Yorkshire, England, to excavate the remains of a medieval timber hall.

Recent excavations unearthed a timber hall measuring 5 metres wide by 16 metres long, which was surrounded by a large ditched enclosure.

The size and shape of the hall is marked by post holes, which the team plan to excavate further to provide new insights into the hall’s purpose and setting in the surrounding landscape.

The hall sits adjacent to a 13-meter-high mound, once presumed to be a motte and bailey castle. However, carbon dating has since revealed its age to be 1,500 years prior to the Norman Conquest era from during the Iron Age.

Dr Jim Leary, from the University of York’s Department of Archaeology, said: “The unearthing of timber buildings dating to the period between the collapse of the Roman Empire and the arrival of the Vikings, a time often referred to as the Dark Ages, is an incredibly rare and significant find.

“The discovery at Skipsea is particularly interesting because we know that the area was in the hands of the last Anglo-Saxon King of England, Harald Godwinson, and then later, after the Norman Conquest of 1066, it became the estate centre of the Lords of Holderness.”

Skipsea was once home to three freshwater lakes, Skipsea Bail Mere, Skipsea Low Mere, and Skipsea Withow Mere, linked to the River Hull through a network of tributaries. These lakes (long-vanished), began 10,000 years ago during the Mesolithic period, and continued into the medieval period.

The lakes were a constant draw to population groups throughout history, which has provided archaeologists with Mesolithic stone tools, animal remains, bone harpoons, and Bronze Age buildings and trackways.
