Historic site of Olloniego

The historic site of Olloniego is a grouping of medieval structures featuring a stone bridge with three arches still standing over the former path of the Nalón River. The location displays the remains of buildings and fortified elements that reveal how trade and travel routes crossed through this strategic point.

This settlement began as a medieval trading point with a bridge crossing the river, followed by the construction of the tower of Muñiz in the 14th century. In the 16th century, authority over the location changed hands, bringing new administrative and economic developments to the area.

The tower of Muñiz dominates the site with its sturdy stone walls that have survived since the 14th century, shaping how the place looks today. Visitors can sense how this fortified structure once controlled the medieval route and marked an important crossroads for merchants and travelers.

The site is easy to reach on foot and the ruins are directly accessible without major obstacles. Wear sturdy shoes since the old stone surfaces and cobblestones are uneven and can become slippery in wet weather.

The river altered its course centuries ago due to severe flooding, leaving the bridge stranded over a dry riverbed where water once flowed. This natural shift transformed the crossing from a working passage into a monument that reveals the power of water to reshape the landscape.
