This, together with the one at Lira, is the longest hórreo in Galicia. Possibly from the mid-17th century, it is a demonstration of the economic power reached by the Galician rural clergy at the time. It is made of stone, with a tiled, two-sided roof. Its external dimensions are 37.05 metres long, 2.40 m wide and 2.70 m high. Two doors open in the longitudinal part, facing the Church of Santa Baia. It is decorated on top with a central cross and two small pyramidal figures at the ends.
