Final answer:
The major difference between Minoan palaces and Mycenaean citadels is that Minoan palaces were sprawling complexes combining government, spiritual, and commercial centers, while Mycenaean citadels were built for protection and fortification.
Step-by-step explanation:
In Minoan architecture, the major difference can be seen in the design of their palaces, which were enormous and interconnected complexes combining government, spiritual, and commercial centers. They had sprawling areas of buildings with thousands of people. The Minoans also valued art, as can be seen in their frescoes depicting athletic events. In contrast, Mycenaean citadels were built for protection and fortification. They had strong walls made of Cyclopean masonry and limited access to the citadel sites. These architectural differences reflect the cultural and functional priorities of each civilization.
