Final answer:
Mycenaean architecture is characterized by its citadel sites with cyclopean masonry and structures like the imposing Lion Gate and the Treasury of Atreus with its significant corbeled vaulting.
Step-by-step explanation:
Mycenae, located in Greece, is famous for its Mycenaean architecture that serves as a testament to the Mycenaean's war-like culture. The cyclopean masonry, large roughly cut stones, formed the basis of their stronghold walls which created formidable citadels on high, rocky outcroppings. These citadels, including prominent structures like the Lion Gate and the tholos tombs such as the Treasury of Atreus, were engineered to provide protection, overlooking the plains used for agriculture and herding.
The Mycenaean citadels' primary architectural feature was the megaron, a reception hall that later influenced the design of Greek temples. Tombs like the Treasury of Atreus showcased corbeled vaulting, where the technique involved offsetting layers of stones to create a beehive-shaped chamber, exemplified by the impressive 44-foot-high vaulted ceiling.
