Buban Fairy Chimneys The Buban Fairy Chimneys located in Oğuldere Village in Sancak town, 50 kilometers outside the city center, are one of the most important features of Bingöl's natural landscape. They're formed by water eroding tuff rock and gently carving beautiful pointed shapes that now represent a natural wonder. The village of Oğuldere (sometimes referred to by its old Armenian name: Buban) is more notable for the short fairy chimneys on many hills surrounding it. The town of Oğuldere is a fairly recent development. The old town was mostly destroyed thirty years ago in an earthquake. A hike from the new to old part of town affords views over green hills, pastureland, and ancient cave homes with fairy chimney-topped hills between them. In addition to the crumbled ruins of the old town, there are a number of caves nearby. Natural ones or homes carved into the rocks, some can be hard to find if you do not ask for directions beforehand.
