The hermitage is located on a former island known as the Isla de la Virgen del Mar.
The sanctuary is dedicated to the patron saint of the city of Santander.
During the annual festival, the statue of the Virgin is transported from the parish church of San Román to the hermitage in a traditional procession.
The structure acts as a nautical landmark for fishing vessels operating along the coast of Santander.
The Ermita de la Virgen del Mar is a hermitage uniquely situated on a small, rocky islet connected to the mainland by a narrow causeway in San Román de la Llanilla. The site serves as the focal point for the annual Fiesta de la Virgen del Mar, the patron saint of Santander. The current building replaced an older structure in the late 19th century. Its position offers views of the Cantabrian Sea and the rugged coastline. The interior houses a religious image of the Virgin Mary, which is carried in a local maritime procession. The islet features steep cliffs that provide a natural barrier against the Atlantic tides. It remains an active site of pilgrimage for local maritime communities.
From the mainland path looking back toward the hermitage during golden hour to capture the contrast between the stone structure and the sea.
Check local tide charts before visiting, as heavy swells can occasionally make the causeway path slippery or inaccessible.
Wear footwear with strong grip due to the uneven, rocky terrain surrounding the islet.
Do not attempt to cross the causeway during high tide or severe weather conditions when waves wash over the path.
The site remains accessible year-round, though the interior may be locked outside of scheduled religious services or the annual festival week.
Respectful attire is required; keep noise levels low as it is an active religious site.
