A relieving triangle is a space (usually triangular) above a lintel in megalithic architecture to relieve the weight of the masonry.
One example of a relieving triangle is the Lion Gate at Mycenae. Two lions in heraldic composition flank a pillar, forming a triangle. The triangle relieves the weight of the corbelled vaulting (in which each successive layer of stones is projected slightly beyond the course below).

Another example of a relieving triangle is from the so-called “Treasury of Atreus,” (which is really a tholos tomb). Here, the relieving triangle is placed over the entrance. Corbelled vaulting was once again utilized in this structure.
