Ermita de Santa Elena & Roman Ruins
On a gentle hill just east of Irún's city centre, the whitewashed Ermita de Santa Elena sits atop a Roman burial ground that is one of the most significant archaeological discoveries in the Basque Country — proof that this crossing point on the Bidasoa has been a strategic hub since at least the 1st century AD. The site is small but genuinely moving.
The Roman cemetery
Excavations begun in the 1970s uncovered dozens of cremation urns, bronze fibulae, ceramic oil lamps and coins spanning the 1st to 4th centuries AD, all associated with a Roman road station that served travellers crossing between Hispania and Gaul at this exact point.
A selection of the finest finds is displayed in Irún's Oiasso Roman Museum in the city centre, but visiting the ermita itself — where original stone funerary stelae are set into the chapel's outer wall — gives the history a tangible, goosebump-inducing physicality.
Oiasso Roman Museum
The Museo Romano Oiasso on Calle Eskoleta is the essential companion visit, housing a meticulously curated collection of artefacts from the Roman port of Oiasso — the ancient name for Irún — including a reconstructed section of the harbour quay and a stunning display of imported amphorae from across the empire.
The museum's interactive maps showing Roman trade routes through the western Pyrenees put Irún's position as a gateway city into vivid perspective — this has always been a place where worlds meet.
Getting there and combining visits
The ermita is a 15-minute uphill walk from the city centre through a quiet residential neighbourhood, and the path continues beyond the chapel into the lower slopes of the Aiako Harriak natural park — making it easy to combine a cultural visit with a short forest walk.
The museum and ermita together take around two hours; finish with lunch at one of the pintxo bars on nearby Calle Aduana to complete a deeply local Irún morning.
