Castell de Fals

Castell de Fals is a medieval defensive complex in Fonollosa, in the Bages region, roughly an hour's drive from Barcelona. Two stone towers and the former parish church of Sant Vicenç de Fals sit on a hillside above the Fonollosa stream, together forming one of the best-preserved examples of frontier architecture in the area.

What should you know before visiting?

The site is also known as Torres de Fals or Castell de Frontera — and that second name is no coincidence. The castle served as a strategic checkpoint controlling the old royal road linking Barcelona and Cardona, opening and closing passage through this border territory. The earliest written references date back to the year 995, when the place appears under names such as Falcas, Falchs and Falcs. It was built during the time of Count Guifré and developed further under Borrell II, belonging from the outset to the domains of the then-young viscountcy of Cardona.

What will you see on site?

Unlike most castles, Castell de Fals doesn't follow a single unified defensive layout — it's made up of two clearly separated towers, each with its own role. The tower on the northeastern side is the oldest surviving part of the whole complex: circular in plan and Romanesque in style, making it particularly valuable to architecture historians. The second tower protected the buildings clustered around the church. Inside, the church of Sant Vicenç has been turned into a small museum space where visitors can learn about the history of the site and the surrounding region.

How do you get there?

Access is via the road connecting Manresa and Calaf. Just before entering Fonollosa, at Molí de Boixeda (kilometre 7.9), a turn-off leads onto the road toward Rajadell. On the left side of that road, at kilometre 3.6, a path branches off leading directly to Torres de Fals. A large free parking esplanade sits right below the castle complex, making it easy to reach by car. The site can also be reached on foot or by bike, following marked trails that connect Fonollosa with the surrounding hills.

When is the best time to visit?

The complex is open for guided visits on the third Sunday of every month, at 10:00 and 11:30. Spaces are limited, so booking ahead is required — the best way is to contact the Tourism and Heritage office of the Fonollosa Town Council in advance. Mornings are a good time to go: the light falls well on the stone towers, and temperatures are comfortable for walking the nearby paths.

Frequently asked questions

Is there parking on site? Yes, there's a large free parking area on the esplanade right below the complex, open to all visitors.

Why is the castle also called Castell de Frontera? Because for centuries it marked a border and control point on the route between Barcelona and Cardona, guarding access to this strategically important frontier region.
