Safranbolu is a district that is preserving its traditional city texture in Karabuk Province. In 1994, the Safranbolu Houses, which represent classical Ottoman architectural features, and the region, were inscribed on the UNESCO World Heritage List. The name Safranbolu comes from the fact that the region was the main saffron plantation region under the Ottomans, and the word Safranbolu roughly means' plenty of saffron’. Until it was conquered by the Ottomans in 1196, it was ruled by different civilizations, including the Romans. Today, it is one of the best-known and most visited districts on the Black Sea coast of Turkey.
