Yacimientos de La Espina del Gallego, Cildá, El Cantón y Campo de Las Cercas

This archaeological complex comprises four distinct areas scattered across multiple municipalities, containing ancient fortifications and military encampments situated in mountainous terrain. The sites include residential structures, defensive walls, and administrative buildings adapted to the steep landscape.

The complex originated during the Cantabrian Wars between 29 and 19 BC, when Roman soldiers occupied indigenous settlements in this mountain region. The remains document how Rome conquered and controlled this territory through military installation and reorganization.

The sites reveal how indigenous and Roman cultures coexisted through the artifacts and coins discovered across different locations.

The sites are distributed across six different municipalities, requiring planning to visit all locations or focus on specific areas of interest. The mountainous terrain and elevation mean a vehicle is necessary, and visitors should be prepared for steep paths and climbing sections.

Excavations at one site uncovered silver coins from the 1st century BC, revealing how this region participated in wider trade networks. This discovery demonstrates economic connections that extended beyond local military conflicts.
