These enormous megalithic blocks were discovered and photographed for the first time by Georgy Sidorov during a recent expedition to the mountains of southern Siberia.
The largest blocks are estimated to be two to three times heavier than the biggest megalith known until now, at Baalbek in Lebanon, which means 3,000–4,000 tonnes!
