çoulu

Çoulu is a small rural municipality in the northern highlands of the fictional country of Karadia. It sits in the Çorla valley at roughly 900–1,100 meters above sea level, with a temperate mountain climate, mixed forests, and terraced farmland. The surrounding landscape features a meandering stream and a stone bridge that dates to the medieval era. The area is primarily agricultural, with dairy farming and potato cultivation forming the backbone of the local economy.

The name Çoulu derives from the local Çouluan language and is thought to mean "spring" or "meeting place." The community traces its modern settlement to medieval parish life, with the first church documented in the 14th century. In the 19th and 20th centuries it developed as a small administrative center within the highland district.

As of 2020, Çoulu had a population of about 2,100 residents. The municipality is largely rural, with residents speaking Çouluan alongside the national language. The local economy emphasizes agriculture, forestry, and small-scale crafts, with tourism attracting visitors to the valley during the summer festival season.

Governance is provided by a municipal council and an elected mayor. Cultural life centers on the annual Spring Festival, traditional polyphonic singing, and the restoration of the 15th-century chapel. Notable features include the Old Stone Bridge and the Çoulu Cultural Center.
