Mill of a Señorina Monument · Arbo, Paradanta, Pontevedra Image of Arbo, not of the place itself. A large water-powered sawmill probably built at the end of the 19th century beside the bridge of San Xoán de Mourentán, on the River Deva; it was completely rebuilt and can now be visited as an example of the comarca's river industry.
