One of the oldest and most historic regions of the country, Port Royal has maintained much of its independence as well as its heritage. Once the enclave of pirates and other outlaws, there is still a strong seafaring tradition. Much of the old city, described in the 17th century as the "wickedest city in the west", lies underwater beside the town, the result of an earthquake that in 1692 swallowed about two-thirds of the then-living space. Since then, another earthquake in 1907, numerous hurricanes, fires, and various population-decimating diseases have plagued the town. Despite all, the waters around Port Royal are a virtual archaeological gold mine, filled with pieces of history that tell of everyday life in the earliest days of English occupation. Port Royal is also home to the Archaeological Division of the Jamaica National Heritage Trust (JNHT), which recently completed a sonar survey of the underwater city, revealing a sunken pirate ship in the Kingston Harbour. To date thousands of artefacts have been recovered, and there are plans to develop a local museum to showcase these items once the research on them is complete.
