On the steep southeastern slopes of the mountain, there is a Tomb of Tantalus dating from this very early period in Anatolian history. This tomb was explored by Charles Texier in 1835, while other schools place Tantalus's tomb, as well as the lake associated with his story, to other localities found on Mount Sipylus. The first location of Smyrna (Old Smyrna) was also at the foot of Mount Yamanlar on what was at the time a small peninsula.
