Ephesus is one of the world's largest and most impressive ancient cities, and also one of Türkiye's most important. Its cultural and historical significance was confirmed by its UNESCO World Heritage status in 2015. The city's ruins lie just 80 km inland from the famous seaside city of İzmir and near the charming towns of Selcuk and Sirince.

In the Aegean region, on a hillside overlooking an area irrigated by the Bakırçay River, lie the ruins of a city known in antiquity as Kaikos. This city was Pergamon, the heart of the ancient world. Its archaeological layers contain significant evidence reflecting the region's remarkable cultural synthesis and the historical continuity of the relationships between these cultures.

The Celsus Library is an ancient Roman architectural structure in Ephesus, Anatolia, located near the modern town of Selçuk, in the İzmir province of western Türkiye. The library has a two-story facade, and inside is a large room measuring between 10.90 and 16.70 meters. This library room sits on a vaulted foundation. The structure is surrounded by an additional wall, which helps protect it from moisture.
