Església vella de Sant Fost de Campsentelles

Església vella de Sant Fost de Campsentelles — the Old Church of Sant Fost — is a set of medieval church ruins standing in the center of the small town of Sant Fost de Campsentelles, in the Vallès Oriental region, Barcelona province. What remains today is modest in size but genuinely old, offering a tangible link to a parish history that stretches back nearly a thousand years.

How old is this church?

The parish of Sant Fost first appears in written records in the year 978, making it one of the older documented church communities in this part of Vallès Oriental. The building whose ruins survive today was formally consecrated on December 4, 1141, by Bishop Arnau de Gurb. That consecration date is closely tied to the apse still visible on site, which is the best-preserved part of the whole structure.

What exactly can you see on site?

The most recognizable surviving feature is a semicircular Romanesque apse, likely dating to the 12th century and kept in reasonably good condition. The original layout combined a single nave closed by this apse with two smaller side absidioles, forming the trilobed chancel typical of Romanesque church design in the region. The remaining wall fragments, while incomplete, are enough to trace the outline of the original building and get a sense of its original scale.

The church once stood on the site of what is now Plaça de les Glòries Catalanes, right in the town center. It survived centuries of continuous religious use, but was destroyed in July 1936 during the Spanish Civil War. Since then it has stood as a preserved ruin — stabilized and made safe for visitors — rather than being rebuilt. Today the site is occasionally used as a venue for local cultural events, which gives it an active, lived-in feel rather than that of a purely static monument.

It's worth knowing that the current parish church of Sant Fost de Campsentelles is a separate, more recent building; parish functions moved elsewhere after the old church was destroyed. The "vella" (old) in the name is a deliberate marker: this is a preserved historic relic, not an active place of worship.

How do you get there?

The ruins sit right in the center of Sant Fost de Campsentelles, a town in Vallès Oriental, close to Barcelona. Because the site occupies part of the main town square, it's easily reachable on foot from anywhere in the center — no extra local transport is needed once you're in town. Sant Fost itself is a comfortable drive or public transport trip from Barcelona, making it a reasonable stop for anyone exploring the quieter corners of Vallès Oriental.

When is the best time to visit?

As an open-air ruin, the site is best visited in good weather — spring or autumn tend to offer the mildest conditions around Barcelona, and the softer light flatters the texture of the old stonework. If a cultural event happens to be scheduled on the grounds during your visit, it's worth checking the local calendar in advance, since the added activity and staging can noticeably change how the site feels.

Is Església vella still an active church? No. It is the ruin of the former parish church, destroyed in 1936. The present-day parish uses a different, newer building elsewhere in town.

What actually survives from the original building? The best-preserved element is the 12th-century Romanesque apse, along with wall fragments that allow the layout of the nave and the two side absidioles to be traced.

How long does a visit take? It's a small site — a relaxed look around takes roughly fifteen to thirty minutes, depending on your interest in Romanesque architecture.

Is it worth combining with other Vallès Oriental attractions? Yes. Sant Fost de Campsentelles is close to Barcelona, so a visit fits easily into a day trip covering other stops in the region.
