Archaeologists working near the Bronze Age arrangement of megaliths known as the Ale Stones in southern Sweden, 10 kilometres southeast of Ystad, have uncovered the remains of what they believe to be the remains of a dolmen (or portal) tomb.
The article is a bit fragmented but indicates that what the archaeologists have found are imprints of the three megaliths that would have formed the uprights of a structure, which would have had a large capstone supported on the uprights. The amount of cementation at the bottom of the imprints indicates that the overlying structure was heavy enough to cause considerable compression.
Unfortunately the excavation was just exploratory and a full exploration will have to wait until a later date, but it does suggest that the Ale area has much more information to offer about the southern Swedish Bronze Age.
There’s a photograph of the 59-stone stone cirle (“in the shape of a 67-metre long ship” according to the article) on the above page.
