Turó del Fanxó, Hill in Castelldefels, Spain

Turó del Fanxó is a limestone hill that rises between Castelldefels and Gavà, reaching just under 280 meters (920 feet) at its peak. Two marked trails start from Cal Ganxo: a shorter one of about 1.1 miles (1.8 km) going directly to the top, and a longer one of about 3.7 miles (6 km) continuing through fields and woods toward the nearby summit of La Morella.

The hill appears in 16th-century records as Puig Pendiu. In the hollow between Can Roca and Montemar stood two large farmhouses: Can Valls del Racó, later called Can Fanxó or Can Fetjó after Joan Romagosa, known as Fetjó, who occupied it in 1817, and Ca n'Orbat, documented from 1184 as Cortils and later as mas Grau. Ca n'Orbat took the name Masia Sant Josep in the 1960s, when it abandoned farming and livestock.

The name Fanxó comes from a local farmer named Joan Romagosa, nicknamed Fetjó, who owned a farm near the hill in the early 1800s. Walkers heading up can still spot the Masia Sant Josep, an old building that recalls the farming life once common in this area.

The climb is accessible to most visitors, but sturdy shoes and enough water are important since the path is rocky and can be dry. Clear days offer the best views from the top, with the Garraf natural area visible in the distance.

The hill was recorded in the 16th century as Puig Pendiu, a name that later fell out of use. The name Fanxó comes from Joan Romagosa, nicknamed Fetjó, who in 1817 occupied the farm Can Valls del Racó; his nickname passed to the farm and then to the hill.
