Castillo de Montehano

Castillo de Montehano is a medieval fortress standing above the town of Escalante in Cantabria, perched on the summit of Monte Hano hill.

Where exactly is the castle located?

The ruins sit at the top of Monte Hano, a hill rising to roughly 187 metres above sea level. The hill was once an island and is now joined to the mainland, forming a kind of peninsula that juts into the landscape of the Escalante municipality. From this vantage point the entire Bay of Santoña opens up below, which explains why this exact spot was chosen for a fortification — controlling the bay was essential for both defence and trade in the area.

Who built it, and when?

The tower was raised in the mid-13th century on the orders of Diego López de Haro, Lord of Vizcaya and Trasmiera, who held these lands between 1243 and 1254. The castle was meant to serve as a control point over the extensive domain of the House of Haro, one of the most powerful noble lines in medieval northern Spain. Its position on a steep, hard-to-reach hill made the site difficult to attack while giving full visual command of the surrounding coast.

What happened to the castle after the Middle Ages?

From the 16th century onward the building fell into gradual ruin, as the region's military and administrative functions shifted elsewhere and upkeep was abandoned. Even so, the site was not entirely forgotten: during the Thirty Years' War (1618–1648) the location regained some defensive relevance. The 20th century added another layer to the hill's story — during the Spanish Civil War (1936–1939) a bunker and a line of trenches were built near the castle ruins, and their traces are still visible in the terrain of Monte Hano today.

Is the castle protected, and can visitors go there?

Castillo de Montehano has held the status of Bien de Interés Cultural since 1993, Spain's top-tier heritage protection category. The land belongs to the municipality of Escalante. Entry is free, but reaching the ruins is not straightforward — the slopes of former quarries around the hill are steep, and thick vegetation makes parts of the climb harder going. It's worth wearing sturdy footwear and allowing extra time, since the ascent tends to be more demanding than it looks from the base of the trail.

Why is it worth the visit?

Beyond its history, Castillo de Montehano is above all a viewpoint — the panorama over the Bay of Santoña and the surrounding mountain range ranks among the most striking in this part of Cantabria. The site layers several eras of history in one compact spot: the medieval fortification of the House of Haro, traces of later conflicts, and 20th-century civil war defences, all on the same hilltop.
