People go to Tarragona for the Romans. An amphitheatre above the sea, a circus, walls, a forum: the city is a UNESCO site for its archaeological ensemble, and guidebooks build the itinerary on that. The cathedral comes at the end of the list, among the things to see if there is time left.
I went in with that expectation, and found myself in front of an alabaster altarpiece that is one of the finest things European Gothic produced. And I discovered that it is the first chapter of a story that closes four hundred kilometres away.
What connects an altarpiece in Tarragona to one in Zaragoza?
One man, one sculptor, two cathedrals
The story is in two names and two dates.
The high altarpiece of Tarragona was commissioned by archbishop Dalmau de Mur i Cervelló and executed between 1426 and 1434 by the sculptor Pere Johan, in polychrome alabaster. Dalmau de Mur was archbishop of Tarragona from 1419 to 1431, and in 1431 he was promoted to the see of Zaragoza, where he remained until 1456.
And here is the point. Once in Zaragoza, Dalmau de Mur wanted an altarpiece for his new cathedral, La Seo, and he called the same sculptor. The high altarpiece of La Seo, the sixteen-metre one reckoned a capital work of late European Gothic, begins precisely in 1434 with Pere Johan’s hand.
So the two works are not two independent masterpieces that resemble one another by chance: they are the same patron and the same sculptor in two stages, first in Catalonia and then in Aragon. If you have seen the altarpiece of La Seo and wondered where that manner came from, the answer is here, and it is eight years older.
The altarpiece of Saint Thecla
The work is dedicated to Saint Thecla, the city’s patron, and it reads in registers.
Along the bottom runs the predella, with six scenes of the Passio Theclae, the saint’s martyrdom, and their detail is the finest work in the whole piece. At the centre stands the figure of the titular saint. Above unfold the stories of the infancy and the passion of Christ, and among the niches you can pick out the patrons’ coats of arms, that of Dalmau de Mur and that of his predecessor Pere Sagarriga.
The alabaster does what it always does: being translucent it does not reflect but holds the light, and the figures look lit from within. Above the registers rises a thicket of gilded pinnacles, extremely fine, which carry the eye up into the apse vault: that contrast between pale stone and gold is the effect the work exists for.
It is worth going close and then stepping back. Close up you read the stories, far off you understand the architecture: they are two different works in the same object.
A Roman temple, a mosque, a cathedral
The cathedral stands at the highest point of the city, and that is no accident: this is where the sacred precinct of Roman Tarraco lay, with the temple of Augustus.
When work began on the Christian church a quantity of reused Roman ashlar went into it, and one corner of the temenos, the wall that closed the ancient cult area, was absorbed into the cloister. Between the temple and the cathedral, though, there was a third building: the mosque of the Muslim city. Reused in the masonry, an Arabic inscription dated to the year 960 survives from it.
If the sequence sounds familiar it is because you have already read it on this site: it is the same as at La Seo in Zaragoza, Roman forum, church, mosque, cathedral. In Spain this is not an exception, it is the normal way places of worship were handed on, and recognising it changes how you look at a building: not a foundation, but the latest layer in a series.
The present church was built from the second half of the 12th century to the 14th, and it shows: the lower parts are Romanesque, the upper Gothic, and the change happens inside the same building without anyone having tried to disguise it.
The cloister, which is the reason you stay
The cloister is the part that held me longest, and also the part almost no guidebook makes anything of.
It measures roughly 46 metres by 46 and is the second largest Romanesque cloister in the Iberian peninsula. The galleries are covered with rib vaults, and the arcades onto the garden are not simple: each bay groups several small arches on paired colonnettes, and in the tympanum above them opens a pierced oculus in a geometric pattern, different from bay to bay. Those openings make the light of the cloister, which comes in as shafts and falls on the ground in patches.
In the middle is a garden with a basin and an orange tree. That is not a romantic detail: the basin stands where the canons needed water, and the cloister was the chapter’s place of work, not an ornamental garden.
One curiosity: among the capitals and impost blocks of the south gallery is the most famous carving in the building, and it is not sacred. It shows the funeral of the cat conducted by the rats: a procession of rats carrying the cat to burial, who then in the following scene turns out to be alive. It is a folk tale carved into a cathedral, and it is proof that the idea of a uniformly solemn Middle Ages is ours and not theirs.
The faces on the corbels, where the building stops being serious
Walking the aisles it is worth looking up at the points where the ribs land on the wall, because several corbels are carved as figures, and they are not devout ones.
The one I photographed is a head pulling its own cheeks with both hands, eyes wide and mouth open, in a grimace halfway between fright and mockery. It still keeps traces of polychromy, which is a reminder of something easily forgotten: these churches were painted, and the grey of the stone that strikes us as austere today is the result of centuries of weathering, not an intention.
Mask corbels exist to carry a load and to amuse whoever looks up. Whoever carved them worked on the same site as whoever made the altarpiece, and the two things sit together perfectly well.
The side chapels
The chapels hold other altarpieces, on a far smaller scale and in different techniques, and it is worth going into them instead of crossing the nave in a straight line.
The one I photographed is composed like a chessboard: painted panels on a pale ground arranged around a central figure of the Virgin and Child, under a cornice of trefoil arches. It belongs to another period and another workshop than the high altarpiece, and the comparison is useful precisely for that: it lines up what a provincial workshop could do against what Pere Johan could do.

The cathedral opens on Sunday only from 14.00, and on Monday an hour later than on other days. Anyone with a single morning in Tarragona who happens to be there on a Sunday would do well to put the Roman amphitheatre in the morning and the cathedral after lunch. Getting there. The cathedral is at the top of the Part Alta, the old town, on Pla de la Seu. From Barcelona the regional train takes a little over an hour, and from Tarragona station it is a twenty-minute walk uphill. How long it takes. An hour and a half, of which at least half an hour in the cloister. An honest warning. If you have one day in Tarragona and the Roman world is what interests you, the amphitheatre and the circus come first. If sculpture is what interests you, the cathedral comes before everything else, and most guidebooks will tell you the opposite.
The sequel to this article is in Aragon: the two cathedrals of Zaragoza hold the altarpiece Pere Johan carved after this one, for the same patron. Staying in Catalonia, Girona has the widest Gothic nave in the world, Barcelona the tallest church and the Seu Vella of Lleida its cloister set in front of the church instead of beside it.
