Iglesia de San Julián y Santa Basilisa

The Iglesia de San Julián y Santa Basilisa is a Renaissance church in Isla, Arnuero, with three naves of equal height that end in a polygonal apse. A square tower rises at the western side of the building.

The building was constructed in the 16th century and underwent major restructuring in 1629, followed by complete rebuilding between 1685 and 1690 under Archbishop Juan Fernández de Isla. These reconstruction phases shaped its current appearance.

Inside you will find a colorful altarpiece from the 17th century showing scenes from the Virgin Mary's life and key biblical stories. These painted scenes fill the view as you look toward the altar.

When visiting, note that the interior unfolds as a carefully designed spatial sequence from the western entrance toward the eastern apse. The architectural details can be best appreciated from different vantage points within the space.

The building stands out for its round columns with Tuscan capitals and ribbed vaults, making it a distinctive example of hall church architecture in Cantabria. This mixed structural form was uncommon in the region.
