0244 – Dating Monte da Contenda

The first two dates are available for Monte da Contenda. The samples were collected in a ditch section where the road cut the enclosure. It is one of the outer ditches of the East sequence of ditches (there is a western one, for the site has at least two sets of ditches partially overlapped).

Due to the pottery recovered in the section we suspected it might be from a middle Neolithic, but the results show that the filling dates from the last three centuries of the 4th millennium BC, showing that the ditch is from Late Neolithic. Nevertheless this ditch defines one of the largest enclosures known in Portugal for this period and confirms Monte da Contenda as a long term complex, since it has an important Chalcolithic occupation as well.

On the other hand, this ditch cuts others. So the probability of the origin of the site is earlier than Late Neolithic still remains.
