Sant Genís de Rocafort

Sant Genís de Rocafort is a Romanesque monastic and defensive complex in the municipality of Martorell, in the Baix Llobregat comarca near Barcelona. What survives today is mainly a roofless church and the ruins of an adjoining castle, both set on a hill on the western edge of town.

When was the monastery founded?

The site's story begins in the eleventh century. On April 8, 1042, Bonfill and his wife Sicarda, lords of Castellví de Rosanes, founded a monastery here. As a foundation tied to a local feudal family rather than a major abbey, the community stayed modest in scale from the start — a detail that helps explain the compact size of the church that has survived. Its independent existence didn't last forever: in 1282, the monastery was absorbed into the Monastery of Sant Miquel de Cruïlles, becoming a dependent priory rather than a self-governing house.

What does the church look like today?

Of the whole monastic complex, essentially only the church remains, and it has lost its roof entirely — the stone walls now stand open to the sky. The building is Romanesque, with construction phases spanning the tenth to twelfth centuries, which points to gradual building and rebuilding across several generations rather than a single campaign. Its plan is rectangular, measuring roughly 18.10 meters long and 5.8 meters wide on the inside. The walls were raised in well-squared blocks of reddish stone, a construction technique typical of small Romanesque churches in this part of Catalonia, and one that shows real care despite the building's modest size.

What's left of the castle next door?

Right beside the church, on the hill's western side, stand the remains of the Castell de Rocafort. The visible wall section and tower are dated to the mid-twelfth century — noticeably later than the oldest parts of the church. Historians link this construction phase to events around 1157, when the feudal lord of Castellví is thought to have broken the Peace and Truce of God (Pau i Treva), a sworn truce meant to protect church property from feudal violence; strengthening or rebuilding the fortification may have followed directly from that breach. What survives is a stretch of wall that closely follows the natural contour of the rock it sits on, plus a round tower with a well-preserved base — the most legible defensive feature left on the site.

Why is this site worth a visit?

Sant Genís de Rocafort brings together two distinct layers of history on a single hilltop: a religious one, tied to a small monastic community founded a thousand years ago, and a military one, tied to feudal conflict among the ruling families of Baix Llobregat. It's an unusually clear place to trace both a Romanesque monastic church and medieval defensive fortifications built within a few generations of each other. For anyone interested in the region's history or Romanesque architecture, it offers raw, unrestored ruins with no tourist infrastructure layered on top — the site as it has actually come down through the centuries.

Where exactly is it located?

The complex sits within the municipality of Martorell, on a hill at the western edge of town, in the Baix Llobregat comarca, Barcelona province. Its approximate coordinates are 41.4654°N, 1.9234°E.

Frequently asked questions

What was Sant Genís de Rocafort? A small monastery founded in 1042 by Bonfill and Sicarda, lords of Castellví de Rosanes, which became a dependent priory of the Monastery of Sant Miquel de Cruïlles from 1282 onward.

What remains on site today? A roofless Romanesque church with a rectangular plan (about 18.10 by 5.8 meters), built of squared reddish stone, plus nearby castle ruins with a wall and round tower dating to the mid-twelfth century.

Why is there a castle next to the monastery? The fortifications likely date from a feudal conflict around 1157, when a lord of the Castellví family is believed to have violated the Peace and Truce of God protecting the monastery's property — the defensive walls appear to be a response to that breach.
