1. There were rumors about the existence of the tunnel. They kind of knew that it existed, but it's written like they did not know where it was.
2. They did not really know who built it, but assumed that ancient Romans did.
3. The tunnel was in "nearly perfect preservation".
4. It was a 60 foot wide single arch tunnel.
5. It was 25% longer than the Thames Tunnel allegedly built by Brunel between 1825 and 1843.
1,300 feet (396 meters) + 25% = 1,625 feet (495 meters)
6. The tunnel was between one of the towers of Fort Saint Nicholas(star fort) and the parish of Saint Victor.
7. The tunnel was built at the "mouth of the port" and went under the "deep sea".
