Prehistoric 7,500-year-old Europe’s largest stone building”, have been discovered
This is poorly written from Bulgaria but interesting
A prehistoric cult complex which is about 7,500 years old, i.e. dating to the Chalcolithic, as well as what has been described as possibly Prehistoric Europes largest stone building, have been discovered by the archaeologists who have resumed the excavations of the Paleolithic and Neolithic settlement on the Big Island in the Durankulak Lake in Bulgarias northeastern-most corner.
The excavations of the Paleolithic and Neolithic settlement on the Big Island in Bulgarias Durankulak Lake first started in 1970s, with the discovered Paleolithic finds dating back to around 10,000 BC; and a Neolithic settlement dating back to between 5500-5400 BC and 5100-5000 BC.
The settlement, which created what is said to be Europes first stone city, belongs to Blatnitsa, the earliest phase of Europes Late Neolithic Hamangia-Durankulak Culture (whose remains are found in todays Black Sea regions of Bulgaria and Romania).
Some of the finds date back to about 10,000 BC, the Paleolithic Age, and there are also numerous finds from all the later periods in Prehistory, and from the Antiquity and the Middle Ages.
The Big Island in the Durankulak Lake, a 3.4 square km lagoon, is known as the Lake City or the European Troy.
It features prehistoric remains from what is said to be the first sedentary agricultural culture in Europe, which created Europes first stone architecture.
The so called Big Island is today a peninsula with an area of 19 decares (app. 4.7 acres, or 0.019 square km).
