The site is to be found right in the town centre of Vilagarcía de Arousa, in one of its green lungs: the Parque do Castriño.

There is material evidence in the area than allows us to talk of an extended period of occupation here, from the Final Bronze Age (8^th century BCE) until the late Roman Age (4^th-5 ^th centuries). From the archaeological excavations carried out up until now, different structures dating back to the second half of the 1 ^st century BCE until the end of the 3^rd century CE have been uncovered.

Its proximity to the sea enabled the hillfort's inhabitants to become skilled fishermen and shellfishers, specialists in catching species such as red bream and cockles, proven by the metal hooks and other utensils related to fishing found here, not to mention the fish remains recovered from the concheiro, or rubbish tip, with remains of shells and bones, which covered a large part of the excavated land and can still be seen today.

The period of greatest prosperity the site experienced dates back to between the 1^st century BCE and the 1^st century CE. After the Roman conquest of the north-western Iberian peninsula (29 BCE-19 CE), Alobre was faced with a new reality. A Roman-Age dwelling unit would be built on top of the remains of the old settlement, and evidence exists of a hypocaust, or heated room, which may have formed a part of a larger thermal complex.
