The pylon or pylon, a word from the Greek πυλών (pylṓn 'large door', 'portal'),[1]​[2]​ is a truncated pyramid-shaped construction "Pyramid (architecture)"), like thick walls, which, erected in pairs, flank the main entrance to the temples of Ancient Egypt; In the space left between the two is the access door.[3] They symbolized the horizon (Axt) through which the sun rises.

Depending on its magnitude and importance, it may be preceded by a dromos, or walk of sphinxes, two obelisks, statues and banners. Behind them there is generally a large open patio, sometimes with a portico on several of its sides. Although they are solid constructions, they usually house passages and stairs for maintenance. It is finished off by a gola at his coronation. Its walls were decorated with polychrome bas-reliefs that narrated exploits of the pharaohs or mythological themes.[4]​.

The most monumental and largest are found in Karnak, erected starting in the New Kingdom. In terms of architectural symbolism, the Egyptian "pylon" has turned out to be an antecedent of the Greco-Roman triumphal arch and preserves many symbolisms common to constructions such as the torana of India, the paifang of China, the Japanese torii, etc.
