The passageway cut down through an overgrown stone paved walkway. We knew that the there was no current railroad service to Sciacca but from that vantage point we could see tracks crossing the stream cut chasm. The tracks disappeared into a tunnel.
We followed the walk down to what was a small complex of buildings that appeared to be a closed terme (baths), "Antiche Terme Selinuntine".
Thus began a question that vexed us throughout our stay. Where was the other end of the tunnel?
Any tunnel would have to pass near under the hill that the new terme was built on and under much of the hill above the port. So under the maze of buildings, stairs, roads and passageways that Joey and I had been climbing almost daily to reach the Piazza Scandaliato level of the town was a tunnel! It seemed unlikely to us that such a long deep tunnel would be possible. But we were wrong.
