There are tombs near Sardis Ancient City, which can be regarded as the ancestor of the modern Manisa and has once been the capital of the Lydian civilization which has introduced the phenomenon of money to the history of human kind, belonging most probably to the Kings and the noble class who have ruled the city. Large and small elevations resembling pyramids have been built on the tombs. This characteristic type of graves is called tumulus. There are 90 units of tumulus in various sizes at Bintepeler. It is believed that the largest tumulus in the region belongs to King Alyattes, the father of Krezüs and to King Gyges.
Almost all of the tombs, which are thought to be built in the 6th or 7th century BC by Lydians during the First Age, are empty, since they have been either destroyed or looted during the First and Middle Ages. Tombs in the region can be seen on both sides of Akhisar - Salihli road.
