Why were reinforced platforms needed for defensive cannon?

In the context of fortification, reinforced platforms were essential for defensive cannon because they were specifically engineered to withstand the intense recoil shock generated when the weapons were fired.1

As gunpowder artillery became more prevalent, engineers had to adapt defensive structures to manage the physical stresses of these heavy weapons. Beyond providing a stable base to absorb recoil, these platforms were part of a broader evolution in military architecture—which included the development of gunports and specialized fortress designs—intended to maintain the integrity of defensive positions against the power of siege artillery. Later, in the 19th century, these concepts evolved into sophisticated traversing carriages and sliding platforms that used gravity, friction, and eventually hydraulic systems to further control and manage the recoil of larger, more powerful guns.12
