The discovery of the Algara treasure Historical milestone · Miño, Betanzos, A Coruña Image of Miño, not of the place itself. On 18 March 1916, at the place called Algara, next to Bermaño, in the parish of Perbes (Miño, A Coruña), around one thousand five hundred Roman coins were discovered, made of silver, copper, tin and low-value silver alloy, known as the treasure of the Algara. The pieces, dated between the years 215 and 268, turned up inside a clay pot while work was being done on a property near the castro dos Mouros, and were eventually sold to collectors. The find confirmed the intensity of Roman settlement at the head of the Betanzos estuary. 1916 Photo: -Merce- (CC BY-SA 2.0) What to see and do in Miño
