Riello

Riello Town Hall

The town of El Castillo belongs to the municipality of Riello, in the province of León, in the Autonomous Community of Castile and León, in the interior of the Omaña region. The municipality is located in a mountainous area on the southern edge of the Cantabrian Mountains and extends along the middle reaches of the Omaña River. According to archaeological evidence, it was inhabited since the Bronze Age, and during the Roman period, its territory was exploited for gold, at the same time as the acculturation of the Asturian populations who inhabited it. From the 14th century, and due to the concessions granted by King Henry II of Castile, the Omaña councils became dependent on the Counts of Luna, who remained legally bound to them until the 19th century.
