The Thracian Tomb of Kazanlak is a vaulted-brickwork "beehive" tomb that is located near the town of Kazanlak in central Bulgaria.
The tomb is part of a large royal Thracian necropolis in the Valley of the Thracian Rulers near their ancient capital of Seuthopolis in a region where more than a thousand tombs of royalty and members of the Thracian aristocracy can be found.
The monument dates back to the fourth century BC and has been on the UNESCO protected World Heritage Site list since 1979. The paintings in this small tomb are Bulgaria's best-preserved artistic masterpieces from the Hellenistic period.
