raving in Arcadia

When Alexander the Great decided to attack the city of Tyre, he ran into a problem: Tyre was an island, and he had no boats. No matter; he had his men construct a bridge amidst the hail of arrows from the walls of Tyre. Then he crossed the bridge and conquered the city.
2500 years later, the centuries of accumulated silt and sand have turned that man-made bridge into a full-scale, permanent geological feature. Tyre is, to this day, no longer an island.
