Caves of Laño and Santorkaria, Ancient cave complex in Condado de Treviño, Spain.

The Caves of Laño and Santorkaria form an underground network of multiple chambers carved into natural rock, each serving specific functions within the complex. The rooms connect through passages, combining residential areas with spaces dedicated to religious practice.

The caves were continuously occupied from the 7th to 11th centuries, with distinct areas developed for living and burial purposes. Archaeological evidence shows they served as an important settlement center throughout this medieval period.

The cave system shows how medieval communities carved out spaces for both daily life and spiritual practice deep underground. Visitors can see the marks of deliberate organization in how the rooms connect and function together.

The caves lie on both banks of the Barruntia stream at Laño, reached by the BU-V-7418 road between Albaina and Laño; the final stretch is on foot only. The route is part of the GR-38 long-distance trail. Las Gobas stands on the western side at Peña del Cerro, Santorkaria on the eastern side.

A small cavity set apart from the rest is known as the Cueva de la Dotora, the "doctor's cave". Local legends say a healer lived there, a courteous and well-educated woman who one day said goodbye and was never heard of again.
