Foca (Phocaea), the holiday town to the north of Izmir, was an important trade center of the ancient world. The Phocaeans, who were also sailors, established trade colonies in various parts of the Mediterrane- an. As a matter of fact, famous cities on the French Riviera such as Marseilles, Nice, and Cannes were founded by the Phocaeans. The song "Marseille" was an old Phocaean folk song taken to France by the Phocaeans, which later became the national anthem of the French (La Marseillaise). There are beautiful coves and islands in the vicinity of Foca. The Siren rocks at the entrance to the Foca harbor are ideal places for sunbathing and diving. Candarli and Dikili are located to the north of Foca. Candarli is worth seeing with its beaches, citadel and ancient city of Pitane. Dikili is an important harbor in the northern Aegean and is known for its beaches.

One of the important historical cities in the Aegean Region is Bergama (Pergamum). The Asclepion, which was one of the largest hospitals in history, is located to the west of the city, which was a great center of culture, art and medicine. Snake reliefs, which were the symbol of Asclepius and later would become the symbol of medical science, are carved at the entrance to the hospital, constructed on behalf of Asclepius, the god of health. Galen of Pergamum, the famous medical scientist, also worked here. The important architectural monuments of Pergamum are located on the acropolis to the east of the town. The famous 200,000 book library, the Temples of Athena and Trajan, the steepest amphitheater in the world and the foundations of the Altar of Zeus, which are among the art wonders of the world, are here (today, all of this magnificent altar is at the Bergama Museum in Berlin).
