It is a millennial olive tree that makes a set with two other olive trees that were transplanted in the year 1978 from the Herdade da Bemposta, near the town of Serpa, where today operates the Professional School for Rural Development. They were placed on the lawn along the aqueduct of the wall of Serpa, at Rua dos Arcos, aligned in the direction N-S. Some trunks are decayed and hollow, forming caves and arches of great landscaping effect. For its unique character, beauty and antiquity, these three olive trees add value to the wall of Serpa.
