Mediterranean fortifications are defensive structures built along the coasts of the Mediterranean Sea to protect against invasions and piracy. These fortifications often include castles, walls, and watchtowers, constructed using local materials like stone and brick. They reflect various architectural styles influenced by the Romans, Byzantines, and Ottomans. Many of these fortifications, such as the Citadel of Aleppo and the Fort Saint Elmo, played crucial roles in historical conflicts. They served not only military purposes but also as symbols of power and control over trade routes. Today, many of these sites are recognized for their historical significance and attract tourists.
