The Mycenaeans built their homes at the top of hills for defensive purposes. Being located at high elevations provided them with a strategic advantage against potential invaders, as they could spot enemies from a distance and defend themselves more effectively. In addition, building their homes at higher elevations made it more difficult for attackers to launch surprise attacks or siege their settlements. The hilltops also provided natural barriers and fortifications, such as rocky outcroppings or steep slopes, which made it harder for attackers to penetrate their defenses. Thus, the defensive advantage was likely the best reason for the Mycenaeans to build their homes at the top of hills.
