Castell de les Espases, Medieval castle in Esparreguera, Spain.

Castell de les Espases is a medieval castle in Esparreguera positioned on rocky terrain near the Llobregat River. The structure includes a circular tower and remaining walls that follow the natural contours of the site, creating a fortified position adapted to the landscape.

The castle is documented from 985, when Count Borrell sold it to Guillem of the Gurb-Queralt lineage, along with the castle of Esparreguera. In September 985 Guillem, whose wife Emma had been captured by Almansor at Barcelona, gave both castles to the see of Vic. In 1351 the monastery of Santa Maria de Montserrat acquired the castles and held the lordship until 1836.

The name "les Espases" comes from the rugged, sword-like ridge where the castle stands, not from the legendary rain of swords. A legend links the site to Count Ramon Borrell's 1003 battle against the Saracens, when God supposedly sent swords from heaven. The chapel, dedicated to Sant Salvador, was documented from the 14th century and served the castle.

The site requires sturdy footwear due to its steep cliffs at the intersection of San Feliu and Vich dioceses. Visitors should consider weather conditions, especially during rain or wind when surfaces become slippery.

The name "les Espases" comes from the rugged, sword-like ridge where the castle stands, not from the legend that God sent a rain of swords to help Count Ramon Borrell defeat the Saracens in 1003. The 413-metre summit is listed among the FEEC's 100 Cims.
