The Neolithic (3800-2200 BC) marks the beginning of crop farming and animal domestication in Britain. It is during this period that we find the earliest evidence of organised human activity in Caerau, the construction of a ‘causewayed enclosure’ in 3600 BC. This makes it 600 years older than Stonehenge.
Consisting of short ditch segments dug concentrically around a hilltop, causewayed enclosures are thought to have been used for important gatherings, such as religious activities, festivals or trade.
Given the effort and coordination required to build such a monument with only stone tools, it was clearly a very important place where people from all over the Cardiff area would have gathered.
