The Arch in question

There were already hundreds gathered before Arch of Triumph, the legendary gates of the city; though it would have been faster to land inside, it was customary to enter Mistral through the arch when attending the festivals, owing back to its earliest days. The arch towered high, decorated in sculptures and engravings featuring thousands of faces and figures—maybe tens of thousands. Thought the opening itself was relatively small, the structure itself was at least a hundred meters tall, nearly twice as wide, and a quarter-kilometer long, expanded by generation after generation of Mistral’s monarchs.
