Hórreo of Quinzán Curiosity · Santiso, Terra de Melide, A Coruña Image of Santiso, not of the place itself. At twenty-one metres long and with seven bays it is the longest hórreo in the concello, testimony to the cereal wealth of the valley of the Ulla; Santiso also preserves the one at Barazón, dated 1793, the oldest in the municipality.
