Church of San Xoán de Argas Monument · San Xoán de Río, Terra de Trives, Ourense Image of San Xoán de Río, not of the place itself. A church of Romanesque origin in the parish of Argas, so heavily restored in the eighteenth century that the Baroque dominates it today; beneath those reforms the lines of its medieval fabric can still be made out.
