Roman ruins of Ammaia

These are the ruins of an ancient Roman city. The settlement was probably founded at the end of the first century BC. It was an important urban center due to its location and the exploitation of mineral and natural resources in the region, such as quartz and gold. It was abandoned during Arab rule. At Quinta do Deão there is a Sítio Museum where the most interesting finds in Ammaia are on display. In 2019, an amphitheater was found in Ammaia, 60 metres wide.
