"Safranbolu is a district and a town of Karabük Province in the Black Sea region of Turkey, about two 200 kilometers north of Ankara and about a 100 kilometers south of the Black Sea coast.
The Old Town preserves many old buildings, with 1008 registered historical artifacts. The Old Town is situated in a deep ravine in a fairly dry area in the rain shadow of the mountains. The New Town can be found on the plateau about two kilometers west of the Old Town. The name of the town derives from saffron, since Safranbolu was a trading place and a center for growing saffron.Today saffron is still alive at the village of Davutobası which is 22 km.east of Safranbolu and probably one of the best quality saffron at the world.
Safranbolu was added to the list of UNESCO World Heritage sites in 1994 due to its well-preserved Ottoman era houses and architecture." - in: wikipédia.
