The church of Sant Serni in Canillo, with its tall bell tower and rocky slopes behind

Sant Serni is Canillo's parish church, in the old village at the foot of the Roc del Quer. Its bell tower, Romanesque in origin and rebuilt in the seventeenth century, is 27 m tall, and the Comú calls it the tallest in the Andorran valleys. The church is mostly Baroque, with a fourteenth-century Gothic crucifix and archaeological remains under the nave. It's open daily from 9:00 to 19:00 and entry is free.

  • Sant Serni is Canillo's parish church, at the foot of the Roc del Quer.
  • Its bell tower is 27 m tall and the Comú calls it the tallest in the valleys.
  • It's Baroque on a Romanesque base, with a Gothic crucifix and remains under the nave.
  • It's open daily from 9:00 to 19:00 and entry is free.

Sant Serni takes twenty minutes and is the best introduction to Canillo. I'd go in to look at the floor of the nave, where the 2009 finds are on show, then step back into the square to see the tower against the rock, which is the village's defining image.

What I would keep in mind

  1. 01 Most beautiful

    A bell tower against a wall of rock

    The church is tucked against the Roc del Quer massif, and the Comú says the two together form a symbol of Canillo's identity. The tower is 27 m tall.

  2. 02 To save money

    Free and open all year

    Entry is free, according to Andorra Turisme, and the Comú gives opening hours of 9:00 to 19:00 every day, with no seasonal variation.

  3. 03 My tip

    Look down as you walk in

    Restoration work in 2009 uncovered structures beneath the nave, possibly from the twelfth-century Romanesque church or an earlier one, plus burials from the seventh to eighteenth centuries. They're displayed in the floor.

  4. 04 Getting there

    In the centre, easy on foot

    It's on plaça de Sant Serni in Canillo's old quarter. Buses L3 and L4 stop in the village, and from there it's a short walk.

    6.8 out of 10

Drive into Canillo and one building catches your eye before any other, a very tall bell tower pressed against a cliff. That’s Sant Serni. I think it’s the most rewarding short visit in the village, because in a quarter of an hour you pick up a good slice of Canillo’s history.

A church pressed against the Roc del Quer

Sant Serni is Canillo’s parish church and, in the Comú’s words, one of the parish’s most emblematic heritage sites. It’s tucked against the Roc del Quer massif, and the Comú says the two together form a symbol of Canillo’s identity. It stands on plaça de Sant Serni in the centre of the old quarter, surrounded by the village’s most historic houses.

The tower is what everyone remembers. It’s Romanesque in origin, was rebuilt in the seventeenth century and stands 27 m tall, which the Comú says makes it the tallest in the Andorran valleys. Andorra Turisme, for its part, gives Santa Eulàlia in Encamp the tallest Lombard Romanesque tower in the country, at 23 m. I don’t read that as a contradiction so much as two different categories, and I’d quote each with its caveat.

What is there to see inside?

Although the first church dates from the twelfth century, the building you see now is mostly Baroque, from the seventeenth and eighteenth centuries, when the nave and tower were substantially remodelled. Traces of the Romanesque structure survive inside and out.

The high altar is dominated by a seventeenth-century Baroque altarpiece dedicated to Sant Serni, a third-century bishop and martyr of Toulouse, shown with mitre and crozier. It mixes painted carving with panel painting, its imagery arranged in several tiers. To my mind, though, the real treasure is on the right-hand side altar, the Santcrist, a painted wooden Christ in folk Gothic style from the late fourteenth century, which the Comú counts among the church’s most valuable pieces.

What turned up under the floor in 2009

In 2009, restoration work exposed archaeological remains beneath the main nave. Studies suggest they may be structures from the twelfth-century Romanesque church or even an earlier building. Burials dating from the seventh to the eighteenth centuries were also found. Everything is displayed in the floor of the nave itself, and it’s the part I wouldn’t miss.

Outside you’ll find fragments of Romanesque wall and an old baptismal font that now serves as a fountain. It’s the kind of detail that makes you look at the square differently.

Opening times and how to fit it in

The Comú lists visiting hours as every day from 9:00 to 19:00, and Andorra Turisme says entry is free. The government’s museums site, museus.ad, gives no hours and just refers to service times, so the two official sources don’t say the same thing. I’d go by the Comú’s, since it runs the church, and make it the first stop of a day in Canillo. Service times aren’t published on the pages I’ve read, so if you’d rather not walk in during Mass, ask at the tourist office first. From there, carry on to Sant Joan de Caselles on the edge of the village, which in summer opens in the morning, 10:00 to 13:00, and again in the afternoon, 16:00 to 19:00.

Being so close to the rock has a practical upside too. The Roc del Quer viewpoint sits at the top of the same massif, and seeing the church from below and then the valley from above is the best way I know to get your bearings.

If you’re curious about the parish’s religious life, you’ll meet Sant Serni again at Meritxell Sanctuary, where the Andorran sculptor Sergi Mas carved figures of each parish’s patron saint. Canillo’s is Sant Serni, alongside Santa Eulàlia for Encamp and Sant Esteve for Andorra la Vella, so the sanctuary works as a sort of roll call of the country’s seven parishes.

Santa Creu, the village’s other church

In the lower part of Canillo, beside the Valira d’Orient in the area known as l’Areny, is the little church of Santa Creu. Andorra Turisme dates it to the fourteenth century, built in the style of Andorran manor houses of the period, and inside is a large altarpiece of 1739 showing the Crucifixion. It’s normally shut and opens as an exception every 14 September, the feast of the Exaltation of the Cross. The path to Meritxell starts beside it, as I explain in Prats.
