How a strategic Mediterranean harbour became the unlikely namesake for a global kitchen staple

In short: The capital of Menorca, Mahón, boasts one of the world's longest natural harbours, a deep-water sanctuary that has drawn empires for millennia. Beyond its naval significance, this city claims a curious culinary legacy: it is the birthplace of mayonnaise, which takes its name directly from the port city itself.

The city of Mahón sits on the eastern coast of Menorca, anchored by a massive natural harbour stretching 5 kilometres long and up to 900 metres wide. Its history is defined by this geography; the name itself is attributed to the Carthaginian general Mago Barca, who allegedly sought refuge there in 205 BC. Throughout the centuries, the harbour's strategic value made it a coveted prize, passing through the hands of the Eastern Roman Empire, the Islamic Caliphate of Córdoba, and the Kingdom of Aragon.

By the 18th century, the port became a focal point of European power struggles. Following the Treaty of Utrecht in 1713, the British occupied the island, transforming Mahón into a vital naval base. They established a Royal Navy Dockyard in 1715 on the north side of the harbour, which remained a primary Mediterranean hub for decades. The British influence was so profound that they moved the island's capital from Ciutadella to Mahón, where it remains the administrative seat for the Island Council of Menorca today.

The city's identity is a blend of military history and cultural exports. While the harbour once hosted warships and the 1711 Royal Naval Hospital, it now supports a modern economy bolstered by tourism and local traditions. Beyond the famous sauce, the city is known for its namesake cheese and a rich history of intellectual figures, including the historian Juan Ramis and the linguist Francesc de Borja Moll i Casasnovas. Despite its turbulent past—including the 1535 Sack of Mahon and 20th-century aerial bombardment—the city has preserved its unique maritime character.
