Alghero: Catalan Gothic, red coral
and the Barceloneta of Sardinia

“In Alghero people still speak Algherese — a Catalan dialect that has survived 600 years far from Barcelona. When you walk its streets you feel that this place has stayed true to itself in a way few towns in the world manage.”

Alghero in a day: the Catalan old town with Santa Maria Cathedral, the Coral Museum (Museo del Corallo) at Villa Costantino, the Archaeological Museum, the towers on the ramparts at sunset and, by boat or on foot, Neptune's Grotto at Capo Caccia (separate ticket).
In summer the old town fills up from the afternoon — arrive early in the morning for crowd-free museums and the best light for photos.

Alghero: six centuries of Catalan identity

In 1353 the Crown of Aragon conquered Alghero and began a Catalan colonisation that would change the town's DNA for ever. The original inhabitants were expelled and replaced by Catalan settlers — from then on Alghero would speak Catalan, build in Catalan Gothic and keep an Iberian culture at the heart of the Sardinian Mediterranean.

Six hundred years later, Algherese still survives — Alghero is the only town in Italy where Catalan is still spoken. The walled old town, the Aragonese towers mirrored in the sea, Santa Maria Cathedral: every stone tells the story of this extraordinary historical anomaly.

In Alghero you walk in a city that has spoken Catalan for over 600 years. It is not a re-enactment — it is a language and a culture that are still alive.

Algherese is protected as a minority language by Italian law and by the Region: you see it in the bilingual street names in the old town and you still hear it in the bars and little shops.

The Coral Museum

The red coral of the Mediterranean — Corallium rubrum — has in Alghero one of its historic capitals. The waters of the Riviera del Corallo, the stretch of coast between Alghero and Bosa, host some of the richest and most prized red coral colonies in the Mediterranean. For centuries Alghero has been one of the historic centres of fishing and craft working of this precious material.

Alghero's Coral Museum tells this story — from traditional harvesting to the coral fishermen's tools and the Sardinian coral jewellery that has come down through the centuries. A small, carefully curated museum in a 1927 Art Nouveau villa, with a scientific section on the life of coral and its protection.

🔴 Coral Museum (Museo del Corallo)

📍 Via XX Settembre 8 · Villa Costantino

The history and art of Mediterranean red coral — from traditional harvesting to handcrafted jewellery. Historic pieces of great value. A quick visit (45 min) but an unforgettable one. Information and opening times on museialghero.it.

Santa Maria Cathedral

📍 Piazza del Duomo · Old town

Catalan Gothic with an Aragonese bell tower. Built between the 16th and 17th centuries, it mixes different styles: the neoclassical façade contrasts with the late Gothic interior.

City Archaeological Museum (MUSA)

📍 Via Carlo Alberto 72 · Old town

It holds finds from the Alghero area, from the Neolithic to the Middle Ages, in three sections: the sea, dwelling and the sacred. Admission charge. Then, about 10 km from town, you can visit the Anghelu Ruju necropolis, part of the “Domus de Janas” UNESCO site since 2025.

Aragonese towers and walls

📍 Seafront

The medieval Aragonese towers around the old town can be visited — some host seasonal exhibitions. The walkway along the sea walls offers one of the most beautiful views in northern Sardinia.
