Fuerte de Santa Elena

Fuerte de Santa Elena is a stone fortress situated on a rocky hill overlooking the Gállego River with rectangular form and several narrow openings. The structure contains underground passages and specially designed chambers for artillery to defend the river valley.

The fortress was built under King Felipe II as part of the border defense system against France and received significant expansions in the 18th century. It played an important defensive role in the Pyrenees valley across several centuries.

The fortress displays Spanish military construction with its thick walls and strategic gun positions designed to control the valley below. You can still see how the cannons were arranged in their chambers to watch over the river and mountain passes.

The climb to the fortress starts from the Santa Elena chapel and crosses the Canonges Bridge leading to the first defensive line. The terrain is steep, so sturdy footwear and time for the ascent are necessary.

During the 1937 war, roughly 350 soldiers and 1500 civilians took shelter in the fortress from heavy bombardment and prolonged siege conditions. Their story connects to a dramatic episode in the civil conflict that swept through this region.
