Bolu is a mid-sized city in the forested mountains of northwestern Turkey, positioned on the historic Istanbul–Ankara corridor. Surrounded by dense forests, mountain lakes, and the Köroğlu range, it is nationally celebrated as Turkey's culinary heartland — chefs from the nearby Mengen district staffed Ottoman palace kitchens for centuries. Today visitors come for Yedigöller National Park, Abant Lake, Kartalkaya ski resort, and the well-preserved Ottoman towns of Mudurnu and Göynük.
Bolu's history spans more than two thousand years. The ancient city of Claudiopolis (from the Latin name given under Roman Emperor Claudius) occupied the same site as today's city. The region passed through Roman, Byzantine, Seljuk, and Ottoman hands. Under the Ottomans, Bolu was part of the Anatolia Eyaleti and became famous for producing the empire's finest chefs from the Mengen district. The folk hero Köroğlu — a Robin Hood-like bandit who championed the poor against Ottoman beys — was born in the Bolu highlands, and his legend permeates local culture. The province's Ottoman-era wooden towns, Mudurnu and Göynük, remain largely intact and are among the finest examples of traditional Anatolian urban fabric in the country.
