History
The town has a long history and the name Mudurnu comes from the Byzantine princess Modrene (Μωδρηνή in Byzantine Greek), and the ruins of the Byzantine castle can still be seen above the town. In the 8th century AD, the forces of the Byzantine usurper Artabasdos, commanded by his son Niketas, were defeated at or near this location by the army of the legitimate emperor Constantine V, before being defeated again at Chrysopolis, the same location where Constantine the Great defeated his Eastern rival Licinius.
In the late 19th and early 20th century, Mudurnu was part of the Kastamonu Vilayet of the Ottoman Empire.
This is an attractive district of forest and mountain. Mudurnu itself is a historical town with a number of well-preserved Ottoman Empire period houses. A portion of the centre of town has been declared an Historic Preservation District ("Kentsel Sit Alanı").
