The 5400-year-old building is buried under an ancient landfill

Archaeologists find the oldest mysterious stone work in Scotland beneath the remains of a Neolithic landfill.

BBC on April 22 reported that a group of archeologists discovered giant stones over 4 meters long while excavating the Stone Age dump in Lake Brodgar in Orkney, Scotland. Stone slabs belong to the wall of a 10m high building, which can be born 5,400 years ago.

According to the expert group, straight stones (orthostats) with rounded edges are used for walling inside ancient buildings and originating from a dismantled stone circle.

"We have never met a mass of megalithic masses in such a large area. The use of stone slabs to build buildings is also different. This indicates that they can be reused and brought from the place. Maybe they are in a circle of stone born before the work found on the lake, all still a mystery , " Nick Card, an archaeologist from the University of Highlands and Islands in Inverness, Scotland. , said.

The ancient dump in Lake Brodgar is one of the largest Neolithic landfills in northern Scotland, serving communities in nearby areas.

Card and colleagues believe the megalithic works they found the earliest in the region. The outer walls of the building are more likely to be built from large stone blocks that are carefully arranged and the surface is more rudimentary. A block of stone is placed on its side to support the straight stones and make them close to the wall.

Archaeologists are still excavating, so it is impossible to accurately assess the scale of the project. This could be a burial site with many rooms or a special role in religious beliefs. However, the reason the project was buried under the landfill was difficult to understand."We can't know when we haven't excavated more , " Card said.
