The ancient structure built in honor of the Sun God in Egypt is the Temple of Ra at Heliopolis, one of the most important religious centers in ancient Egypt. Heliopolis, meaning "City of the Sun," revered Ra, the sun deity, and was prominent in the worship of the sun throughout various periods of ancient Egyptian history. The temple complex featured large stone obelisks and was a center for astronomical studies and royal rituals. Although much of the original structure has since been destroyed, its legacy continues to influence discussions about ancient Egyptian religion and architecture, symbolizing the civilization's deep connection to solar worship.
