Are there any graves of the heroes of Trojan War?

One of the main subjects of the excavations since 1863 is the place of the burial place (nekropol) of Troy. Schliemann's, Dörpfeld's and works of others didn't give any result. Only Bergen excavations in 1930's a small burial place on the lower city from 1300's B.C.E. was found, but the reearchers on it didn't give us any concrete information. Therefore we don't have conclusive information on Troy I (3000 B.C.E.) and Homeric Troy of Troy VI-VII with regard of burial places. In this sense it is difficult to say anything about the graves of the Trojans. However, Homer experts determined that the burial ceremonies decribed in the Iliad have indeed an old history. Patraklos' burial in the 23th episode and Hector's burial in the 24th and last episode of the Iliad, a detailed description is given how their corpses was put on fire.

Whereas in Mycenaen peried this fire ritual is not seen a lot, after the 11th century B.C.E. it became widespread. In the epic, corpses of all heroes, Achaen or Trojan, are burned and buried in a pot. The findings with regard of this tradition of late Bronze Age are found both in Greece and in Beşik Koyu (coast of Troy) by Korfmann's excavation in 1986. But the tumulus mentioned in the Iliad is not yet found. The all tumuli to be seen around Troy belong to an period around 1000 years later (Hellenistic or Roman Period) and somthing like monumental tomb couldn't be find from the times of Homeric Troy.
