All Pirate Stories are not Legend: 1-Pirate tunnels

In Savannah, Georgia there is a network of tunnels that may have been used by pirates to rob the city and capture prisoners. There is one passage that leads to the river where boats possibly waited for their crew to return with the spoils of their pillaging.

Some of these tunnels are no long accessible due to a major collapse some years ago. Some theories claim the tunnels may have been used by secret societies to carry out conspiracies against the government.
