Necropoli Li Muri

The earliest megalithic remains on Sardinia, probably dating from the early
Ozieri period, perhaps about 2500 BC.
North Sardinia. 8 km from Arzachena.
Five intersecting circles, the largest 7.6 m in diameter. In the centre of
each circle is a cist with stone paving around it and a surrounding circle of
upright slabs mixed with slender standing stones.
