Oia town hall

Oia town hall stands in O Arrabal, the main settlement of the municipality of Oia, on the Pontevedra coast in Galicia. This modest historic building no longer serves the purpose it was built for, and its street, Vicente López, doubles as the settlement's main promenade.

What is this building?

The old town hall of Oia was built in 1875. For decades it housed the local administration, but today its rooms hold the municipal tourist information office instead. The building is marked by a plaque at the start of Vicente López street, which points to its former role. That same street has long been the obligatory crossing point for anyone heading into the settlement, which is why it functions as the natural centre of O Arrabal.

Where is O Arrabal located?

O Arrabal is a small village — home to roughly 239 residents according to 2022 statistics — and it serves as the administrative seat of the Oia municipality, in the Baixo Miño area on the southern Pontevedra coast. The village grew up right next to the Monastery of Santa María de Oia and still keeps its narrow lanes, small squares and traditional Galician houses, several of which have been restored into guesthouses and places to eat.

What else is worth seeing nearby?

A short walk from the town hall stands the Monastery of Santa María de Oia, a 12th-century Cistercian complex recognised as an Asset of Cultural Interest (Bien de Interés Cultural). It is the only Cistercian monastery in Europe built directly on the shoreline, which alone makes it an unusual architectural stop.

Also worth a look is Plaza Centinela, a square dating from 1764 that once served as a lookout point guarding the village against attacks from the sea. Its stone balustrade offers views over the harbour and the monastery, and the square holds a small chapel with striking religious imagery depicting souls in purgatory.

Don't skip "A Camboa" either — a traditional stone weir system once operated by monks, using a sluice gate to control the tidal inlet. It becomes visible at low tide, viewable from around Plaza Centinela.

When is the best time to visit?

O Arrabal is best explored as part of a longer coastal walk, pairing a stop at the old town hall — now the tourist office — with the monastery and Plaza Centinela. Given the village's small size, the centre itself takes little time to see, so it's worth building it into a broader route through the Oia municipality and the Rías Baixas coastline.
