I have never found such a strange situation before. Close to each other there are two mausolea. Their names are Kalender Baba Türbesi and Kesikbaş Türbesi (türbe is mausoleum). However, if one tries to identify them, it becomes a mess. I can find pictures of either with the name of the other. The same for articles: I found an article where the names I now use are under pictures identifying them as such, then I found an article about the Kesikbaş Türbesi in a local newspaper, with a picture of the Kalender Baba Türbesi. So I give up: this is either the one or the other. If you want to know more, do your own research, at your own peril.
