Kütüklü Baba was a Bektashi dervish associated with the early Ottoman frontier and the household of Gazi Evrenos. His octagonal domed türbe near Selino in Xanthi, Western Thrace, Greece, is dated on architectural grounds to the late 15th–early 16th century. Only the stone mausoleum survives of what was once a tekke complex. (Sources: Wikipedia 'Kütüklü Baba Tekke'; Heath W.
