Cova d'en Daina, Spain
Cova d'en Daina was built out of granite blocks and is dated to around 2700-2200 BC. It was discovered by Pere Cama I Casas and the first mention of its uncovering was by Agustí Casas in 1894. It was later excavated by Lluís Esteva Cruañas, who unearthed human bones and teeth, flint arrowheads, knife and pottery fragments and necklace beads. It was partially reconstructed in the 1950s. It is seven metres long and made up of an entrance passage into the funeral chamber, with a circular tumulus that is 10 metres in diameter. The entrance to the tomb is oriented to the southeast, which allows sunlight to reach the interior on the summer and winter solstices.
We saw this marked on the map when we were looking for somewhere to park for the night after driving over the border from France. It is a lovely quiet site amongst woodland with a good sized area to park. Worth a visit if you are nearby.
