The road is covered by 25 feet of water. If the Romans built the road 10 ft above sea level, that means the sea rose 35 feet in the past 2,000 to 2,500 years. I don’t think so.
The area around Venice is a marsh.
The land may have very well sunk 35 feet in 2000 years.
Not so fast. What is called “sea level rising” is also base level of terrain sinking which people perceive as rising seas. It can easily be the case.
The landing beaches of Caesar in England are now a half mile inland. The sea is about a mile from Thermopylae today also.
It is very probable that this road is exactly when they claim. Also it’s easily proven due to Roman road building techniques.
