Perdigões ditch 7, another one with structured depositions and human remains, is now also dated by three radiocarbon dates that put its filling and re-cuttings between 2600 and 2200 BC. This ditch has one of the most interesting sequences of filling of Perdigões ditches, for it has a sequence of depositions that seem to have been deliberately closed by a stone “cairn”. After that the process of filling changed. That sequence is well dated by these three dates. But some more are needed.
