The Hórreo de Lira is a fine example of Galicia's long raised granaries, built to keep grain dry and away from animals in the damp Atlantic climate. Its length and stone rhythm make it more than a rustic curiosity; it is one of the structures that gives this part of the coast its local character.
It is a simple stop, best paired with the harbour villages and beaches south of Muros. Go for the architecture and the setting rather than a museum-style visit, and take a moment to compare it with the smaller hórreos you will see across rural Galicia.
