Orthostatics are the upright stones that form the walls of megalithic structures, such as Stonehenge. Orthostatics are typically large, flat slabs of stone that are set upright in the ground. They are often used to create walls, but can also be used to create other structures, such as doorways and windows.
Checking orthostatics is an important part of maintaining megalithic structures. Over time, orthostatics can become loose or damaged, which can compromise the stability of the structure. Checking orthostatics involves inspecting them for any signs of damage, such as cracks, chips, or loose stones. If any damage is found, it should be repaired as soon as possible to prevent further damage to the structure.
