History of Alghero

Ancient Origins of Alghero

Alghero, located on the northwest coast of Sardinia, has a history that dates back to ancient times. The area was originally inhabited by the Nuragic people, whose presence is still evident in the numerous Nuragic structures found throughout the region. The Phoenicians and later the Carthaginians established trading posts along the Sardinian coast, including in the area around Alghero. However, it wasn’t until the Middle Ages that Alghero began to take shape as a significant settlement.

Alghero During the Medieval Period

In the 11th century, the Genoese Doria family established Alghero as a fortified town. The strategic location of Alghero made it an important military and trading outpost. The Genoese fortified the town, building walls and towers that still stand today. In the mid-14th century, the Crown of Aragon conquered Alghero, leading to a significant cultural and demographic shift. The Catalan-Aragonese influence remains strong in Alghero, with the Catalan language still spoken by many locals, and the town often referred to as “Barceloneta” or “Little Barcelona.”

Alghero Under Spanish and Savoyard Rule

After the Aragonese, Alghero came under Spanish rule as part of the Kingdom of Sardinia. The town continued to thrive as a maritime center, with its port playing a crucial role in trade and military defense. The Spanish influence is still visible in Alghero’s architecture, language, and customs. In the early 18th century, Alghero, along with the rest of Sardinia, was transferred to the House of Savoy following the Treaty of Utrecht. Under Savoyard rule, Alghero experienced modernization and development, while still maintaining its distinct Catalan character.

Modern History of Alghero

In the 19th and 20th centuries, Alghero evolved from a fortified town into a vibrant community, known for its rich cultural heritage and natural beauty. During World War II, Alghero was strategically important and suffered some damage, but it was quickly restored post-war. Today, Alghero is a popular tourist destination, celebrated for its well-preserved medieval old town, stunning coastal landscapes, and its unique blend of Italian and Catalan cultures. The town has successfully preserved its historical charm while embracing modern tourism, making it one of Sardinia’s most beloved destinations.
