Castro de Santa Trega

The most significant archaeological site occupies a 20 hectares area, of which only a small part of it has been dug. The documented origins are from the 4th-century b.C.; it reached its most crucial development in the changing era. In the peninsula of the Trega, an indeed city was developed, with a population of between 3000 and 5000 inhabitants, where the Mediterranean and Atlantic cultures were meeting. The Society Pro Monte, founded in 1912 thanks to the interest of the indianos (“returned emigrants”) from A Guarda, undertook the first archaeological excavation campaigns on which participate Ignacio Calvo, Cayetano Mergelina, Manuel Fernández and De la Peña Santos successively.

Capilla de Santa Trega

At the San Francisco peak is placed the Santa Trega hermitage. Possibly the nun Egeria after to come back of her pilgrimage to Orient, encouraged the devotion for Saint Thecla to the Baixo Miño hermits at the High Middle Ages. Although we have already recorded the existence of a hermitage in this location since the 12th century, it was with the renovations and enlargements at the 16th and 17th centuries that attained its current appearance. The archaeological excavations made in 1994 led to the discovery of several Visigoth’s sepulchres that showed the religiosity of the place.

CROSSES & CRUCEIRO (stone cross)

Various religious festivities are celebrating along the year as a sign of the critical religious tradition and the worship of the martyr from Iconium. Such as the romeria (in which the families spend the day together in the mountain with a typical meal) on September 23rd in her honour or the hundred-year-old procession of Voto, that takes place on the last Saturday of August. On the march, the devotees go through the stations of the modern Via Crucis (Way of the Cross), a Vincent Mengual’s work, a sculptor from Valencia, that replaced the previous one that made in a more plain style. In front of the hermitage rises a 16th-century cruceiro (stone cross), dedicated to San Francisco, that remembers the presence of the order in A Insua, the small Portuguese island just at the confluence of the river and the sea.
