This was a monumental access gateway to the holy space that surrounded a giant temple used as a place of worship in imperial times.
This semicircular arch, today with a height of 15 metres from the top of the supports, was the central opening in a gateway consisting of three arches, of which the side arches were smaller and flatter. The whole structure was made of granite blocks.
