Dume enjoyed in earlier times a relief situation especially in the sixth century during the reign of
Theodemar king of the
Suebi. His father,
Chararic, invoked
Saint Martin of Tours, when Theodemar was affected by a disease in childhood. After obtaining the cure in 550, he founded a church in Dume and sent emissaries to
Gaul in search of relics of the saint. By providential provision, the emissaries of the king met with
Martin of Pannonia (later to be canonized and known as Martin of Dume), who was heading from
Jerusalem to Gaul, to the tomb of his namesake and compatriot. That meeting showed him the place where it should go to exercise his apostolate, because until then the Suebi had professed
Arianism. He landed possibly in
Portus Cale, where he went to
Braga, to the court of Theodemar, completing the king's conversion, with the help of the bishop Eleutério and the bishop of
Coimbra, Lucêncio. From Theodemar he obtained the newly founded Church of Dume, next to whom he built the
Monastery of Dumio. So remarkable became his action that in 558 it was elevated to the episcopal dignity, turning the church into a cathedral, the area of the monastery becoming the Bishopric of Dume. With the
Christian reconquest, after the
Muslim invasion, the small diocese of Dume became embedded in Braga. The ancient parish of São Martinho de Dume was one resignation from the patronage of the presentation of the prelate of Braga. In the parish there are several chapels, including one in the
Romanesque style, in place of the Order, headed by S. Lawrence. It is tradition to have worked in this chapel the
canon of the
Cathedral of Braga, in a time that an epidemic was raging in the city. At the place of Cabanas, there is a
Manor house with a chapel, where on 25 December 1888, the resigning Archbishop of Braga
Dom João Crisóstomo de Amorim Pessoa died. According to tradition a great battle against the
Moors occurred in this parish and in the places of
Anteportas and
Sobremoure. == Ecclesiastical history ==
