The Church of Fiães, is a Romanesque and Baroque era Portuguese religious building located in the municipality of Melgaço, in the northern district of Viana do Castelo. Originally a Roman-Cistercian church, it was remodeled during the 17th and early 18th century in the Baroque style, but still exemplifies many of the characteristics of the early building (typifying the Galician Cisterian monasteries and Minhota churches of the time).
