What is left of the Kaineus Tomb, near the Kafi Baba Dervish Lodge, in necropolis area 3. As a result of geographical collapses a spring flows from the lower burial chamber of a monumental tomb, which is thought to have been two-storied. It used to be thought part of a water monument, but later it was understood to have been a structure like the Xñtabura tomb after part of the upper structure was discovered nearby.
