Ermita de Santa Elena & Roman Road
A ten-minute walk from Irún's old town, the modest Ermita de Santa Elena sits atop a low hill that conceals one of the most significant Roman archaeological sites in the Basque Country — excavations beneath and around the chapel have revealed a Roman road, a necropolis and votive altars dating to the 1st–3rd centuries AD. Almost no tourists come here, which makes it all the more rewarding.
The site and what survives
The Roman road visible in the excavated trench beside the ermita formed part of the Via Aquitania, the imperial highway linking Hispania with Gaul — you can stand on the same paving stones that Roman legions and merchants walked two thousand years ago. Interpretive panels in Spanish and Euskara explain the finds clearly.
The ermita itself is a simple whitewashed chapel from the 16th century built, as was common, directly over a pagan sacred site to Christianise it. The combination of Roman, pre-Roman and medieval layers in one small hilltop is quietly extraordinary.
Getting there and combining visits
The site is reached via a short signed footpath from the Calle Santiago area near the old town; the climb takes about 10 minutes and the hilltop offers a pleasant view over the Bidasoa valley and the rooftops of Irún.
Combine the visit with a walk down to the Puente Internacional (15 minutes on foot) for a morning that spans two millennia of cross-border movement in a single easy loop.
