Dive into the heart of Calvi, an ancient Genoese city, to unravel the mystery of Christopher Columbus and his Corsican legacy.
« Civitas Calvi semper Fidelis »— , Inscription carved on the Genoa Gate, Calvi (attested since 1553)
Your journey in Calvi begins at the Marina, inaugurated in 1960, capable of accommodating 500 berths. This location was a Genoese naval base as early as the 14th century, essential for Corsican maritime trade. Observing the citadel from a distance, imagine the merchant ships from the time of Christopher Columbus, whose remains are traditionally said to have been housed in Calvi. This site, though modern, offers you a direct panorama of the Calvi Citadel, built by the Genoese in the 13th century and classified as a Historic Monument in 1975, which will be the setting for your investigation.
Pass through the Porte de Gênes (Genoa Gate), the sole surviving entrance to the Genoese citadel, erected around 1490. This 8-meter-high gate, whose original drawbridge was replaced in 1800, is the main access point for your journey into Corsican cultural heritage. It is here that the inscription 'Civitas Calvi semper Fidelis' has been carved since 1553, recalling Calvi's loyalty. As you explore the 1 km long ramparts, you will trace the 110-day siege of 1794, led by the French under General Samson Augustin, against the British forces of Nelson Horatio.
Your path then leads you to the Place d'Armes, developed in the 16th century by the Genoese. This 800 m² square, surrounded by 17th-century administrative buildings, was a crucial site for military gatherings during the 1794 siege. From here, you have a direct view of the nearby Tour de Sel (Salt Tower), a relic testifying to Calvi's strategic and economic importance. The European Heritage Days highlight these structures that narrate the city's history.
Continue your investigation at the Palais des Gouverneurs (Governors' Palace), a 15th-century Genoese building of 500 m² over two floors, residence of podestats like Luciano di Wiese from 1278, when Calvi became an administrative center. This palace hosted Christopher Columbus according to a local claim in 1490, a fact your archivist mission must verify. Restored in 1985 by the Tourist Office, this edifice immerses you in the intrigues of the powerful Republic of Genoa.
Your quest concludes at the Cathédrale Saint-Jean-Baptiste, the citadel's main church, rebuilt in 1772 after a fire in 1794, then restored in 2007 following an arson attack. Its baroque style and single 20-meter-long nave housed the remains of Christopher Columbus according to a historically unconfirmed tradition. By exploring this Calvi citadel, you will not only have discovered a historic site classified since 1975, but also gathered clues to unravel the threads of this enigma, enriching your understanding of Corsican heritage and the history of Calvi.
