Grave Circle A in Mycenae is a 16th century BC royal cemetery situated on the southeast of the Lion Gate, the main entrance of the Bronze Age citadel of Mycenae, southern Greece. The site was initially constructed outside the fortification walls of Mycenae, but was ultimately enclosed in the acropolis when the fortifications were extended during the 13th century BC. Grave Circle A, as well as Grave Circle B, the latter found outside the walls of Mycenae, represent one of the major characteristics of the early phase of the Mycenaean civilization.
