Salbyk kurgan

It is located in the "Valley of the Kings" in the western part of the Minusinsk hollow, 45 kilometers northwest of Abakan, Khakassia, Russia, and is dated to 500-300 BCE.

The tumulus is surrounded by huge Devonian slabs, weighing 50-70 tons, which were brought over about 100 kilometers from the banks of the Yenisei River.

They are arranged in a square, with horizontal slabs forming a wall enclosure.

The megaliths may have had an astronomical role and seem to correspond to the position of the sunrises and sunsets at various times of the year.

It was excavated in 1954-56 by removing all the earth of the kurgan, only leaving in place the monumental slabs on the periphery.
