There is a fifteenth-century Italian painting that nobody studies at school, and not because it is minor: because it is not Italian. The National Art Gallery of Cagliari holds the most important collection in the world of Sardinian-Catalan retablos, the great painted altarpieces made in Sardinia when the island belonged to the Crown of Aragon and looked towards Barcelona and Valencia rather than Florence.
The consequence is visible the moment you walk in. There is no perspective of the kind Piero built, no Florentine drawing, no Italian way of letting figures breathe in space. There is gold laid across the whole ground, there are carved and gilded gothic architectures, and there are faces painted with a realism that comes from the Netherlands by way of Spain.
The museum occupies three floors of the Cittadella dei Musei, above the archaeological museum, and hardly anyone gets there because hardly anyone knows it exists. It is the quietest room in Cagliari.
What a retablo is, and why Sardinia has them
What is the difference between a retablo and an ordinary altarpiece? An Italian altarpiece is almost always a single panel inside a frame. A retablo is a piece of architecture: dozens of painted compartments mounted on a carved and gilded wooden frame, up to five metres high, with a predella at the bottom telling stories in miniature, the main compartments in the centre, saints in the side wings and a crowning tier on top.
It was made to cover the whole wall behind the altar, and to tell stories in pictures to people who could not read. It is the typical form of Mediterranean Spain, and it reaches Sardinia with the kings of Aragon, who ruled the island from the fourteenth century.
In the early fifteenth century retablos are ordered directly in Catalonia and arrive by sea. Then the interesting thing happens: the workshops move to Cagliari, and the painting becomes Sardinian.
The San Bernardino retablo, and the predella that lost half of itself
The piece of 1455 signed by Joan Figuera and Rafael Thomas is the document of that passage. Of the original structure the gallery also shows the predella, which is the photograph that opens this article, and which is worth looking at closely for two reasons.
The first is that it works as a row of portraits. Under a run of gilded gothic arches, seven half-length figures lean out over a parapet: a man in black with a book, Saint Michael in armour with red wings and a cross on his tunic, the Baptist with the lamb, at the centre the dead Christ held up by an angel, then a bearded bishop with an open red book and a crozier, a knight in a plumed hat, and Saint Paul with his sword.
The second reason is blunter: half the panel has no colour left. Below the line of the parapets there is nothing but the pale, bare gesso ground. Nobody has repainted it, and that is the right restoration decision: you can see how a panel is built underneath the painting.
The Master of Castelsardo, the island’s finest anonymous painter
We do not know his name. Art historians christened him the Master of Castelsardo after the place of one of his retablos, and he worked between the end of the fifteenth century and the beginning of the sixteenth.
The compartment above comes from his Porziuncola retablo, now dismembered, and shows the preaching of Saint Francis. The saint stands top left on a stone pulpit, painted in pale, steady tones that make him look like a statue. All the rest of the panel is taken up by his listeners: a bishop in mitre and embroidered cope, a hooded friar, men in green and red hats, one holding his head in his hands, another seated on a wooden chair with his back to us.
Look at the faces one by one, because that is where the novelty lies. They are not types: they are different people, with different noses and different ages, painted by someone who had seen Flemish painting. In a Sardinian church around 1500 this was a new world.
The Saint Eligius retablo and its losses
The Master of Sanluri, by convention, signs this structure dedicated to Saint Eligius, the bishop of Noyon who was a goldsmith by trade and is the patron of goldsmiths and farriers.
It is the retablo that best conveys the structure, because it is displayed almost complete, with the side wings open like a cupboard. The saint sits enthroned at the centre, bishops and saints fill the compartments around him, Saint Sebastian is tied to his tree on the right; along the bottom runs a gilded predella with six scenes from the saint’s life, tiny and crowded.
Here too the loss is part of the work. Several compartments have lost their colour and are left as empty fields of gold with islands of surviving paint: seeing it beside Figuera’s predella shows how little it takes for five centuries to carry a story away.
The Cavaro family, the Stampace workshop
In the sixteenth century Sardinian painting finally has names, and almost all of them belong to the same family. The Cavaro workshop worked in the Cagliari district of Stampace, at the foot of Castello, and ran through three generations: Lorenzo, then Pietro, who is the strongest, then his son Michele.
Pietro Cavaro’s Vision of Saint Augustine is the panel you will not walk away from. The saint stands at the centre in a black habit and gold stole, crozier in hand and his mitre set on the ground at his feet, his eyes raised. On either side, beyond a low wall, two visions open: on the left the Crucifix in a landscape, on the right the Virgin nursing the Child, seated and dressed in white.
What strikes you is the choice of colour. The painter gives up gold and builds everything on whites, greys and dulled golds, with a single note of blue in the sky on the left. This is mature Spanish painting, with the air of the early sixteenth century, made in a city eight hundred kilometres of sea from Valencia.
The Last Judgement, and how to look at a dismembered retablo
The last room lines up what survives of the Last Judgement retablo, attributed to the workshop of Lorenzo Cavaro, and it serves as a lesson in how these works reached us.
You see two tall narrow panels hung side by side like pictures. They were not pictures: they were two wings of a structure that had many more. Each carries two registers. Top left an Annunciation, with the red-winged angel; top right the Adoration of the Magi before a hut. In the lower register on the left is the Judgement: Christ in glory among the blessed, the risen coming out of the earth and, at the bottom, a hell crowded with devils and bodies. On the right two standing saints, one of them Saint Anthony Abbot, in black, with his staff, his bell and a red book, and at their feet a small kneeling donor.
Why are almost all the gallery’s retablos in pieces? Because in the eighteenth and nineteenth centuries Sardinian churches rebuilt their altars in the new style, and the wooden structures were taken apart and sold off piecemeal. The museum has recomposed what it could and leaves the rest in scattered order, which is more honest than an invented reconstruction.
Practical information
Details checked on 7 September 2026 by cross-referencing SardegnaCultura, the portal of the region of Sardinia, and Cagliari Turismo, the city council’s portal, because the official site of the national museums of Cagliari refuses automated requests. Prices and hours change: check again before you travel.
Tickets. The ticket is shared with the National Archaeological Museum and costs 10 euros; it also covers the sixteenth-century Cannoniera. The reduced ticket costs 5 euros, while visitors aged 18 to 25 pay 2 euros.
Careful: the art gallery is entered only from the archaeological museum. The ticket office and the bookshop are there, and no independent entrance exists. If your time is short, buying the ticket still means crossing the other museum.
Hours. The gallery opens every day 8:30-19:30, with the ticket office closing at 18:45. There is no weekly closure.
Free entry. Entry is free for under-18s and for the other categories set by national rules, and on the first Sunday of the month it is free for everyone.
Getting there. The address is piazza Arsenale, inside the Cittadella dei Musei, in the Castello quarter. From the central station it is a twenty-minute walk up past the Bastione, which also has a public lift.
How long it takes. An hour and a quarter for the three floors. With forty minutes, stay on the floor of the fifteenth-century retablos and skip the twentieth century.
How to fit it into the day
The gallery shares its ticket, its door and its hours with the archaeological museum, so the question is not whether to see it but how much time to give it. The advice, having tried it: come in here first, while your eyes are fresh, and move on to the archaeological museum afterwards, which is longer and more tiring.
The Nuragic bronzes of the archaeological museum are in the same building. Walking down towards piazza Palazzo you reach the cathedral of Santa Maria in five minutes, where sixteenth-century Sardinian painting returns in the chapels, and further down, outside the walls, are the basilica of San Saturnino and the Tuvixeddu necropolis.
The gallery sits in the museum citadel, inside the same walls as the archaeological museum: how the two fit into one day is what I set out in what to see in Cagliari in two days.
