Dolmen di Sa Coveccada

The Dolmen di Sa Coveccada is a prehistoric megalithic structure located in the northern region of Sardinia, Italy. It is situated near the town of Arzachena, in the Gallura sub-region of the island.

The dolmen is thought to date back to the Bronze Age, around 3000-2700 BCE, and is one of several such structures found in the area. It consists of a large central chamber, formed by four vertical slabs and a large capstone, which is estimated to weigh around 80 tons. The entrance to the chamber is marked by two large standing stones, and there is also evidence of a smaller external chamber.

The purpose of the dolmen is not entirely clear, but it is believed to have been used for burial rituals and may have had a symbolic or religious significance for the people who constructed it. Similar structures can be found throughout Europe, from Ireland to the Mediterranean, and they are considered to be some of the earliest examples of monumental architecture.

Today, the Dolmen di Sa Coveccada is a popular tourist attraction and is accessible to visitors who wish to explore its ancient chambers and learn more about the history of the region. It is also part of a wider network of archaeological sites in Sardinia, which include numerous other megalithic structures, nuraghi (ancient fortified towers), and other remnants of the island's prehistoric past.
