How the wickedest city on Earth sank into the sea in a single day
In short: Once the most prosperous hub in the Caribbean, Port Royal was a notorious pirate republic fueled by stolen Spanish gold. In 1692, a catastrophic earthquake turned its sandy foundation into liquid, dragging half the city beneath the waves. Today, this sunken metropolis offers a rare, frozen glimpse into colonial life.
Founded by the Spanish in 1494, Port Royal eventually became an English stronghold and a magnet for privateers. By the late 17th century, it was a legendary site of excess, where merchants and buccaneers collaborated in forced trade to plunder Spanish wealth. The city grew so wealthy that its privateering profits vastly eclipsed the income generated by the island's entire sugar industry. This era of decadence earned it a reputation as the Sodom of the New World, with taverns and gambling houses catering to sailors who spent fortunes in single nights.
The city's rapid expansion proved to be its undoing. Built on a narrow spit of water-saturated sand, the town lacked a stable foundation. On 7 June 1692, at 11:43 a.m., a massive earthquake triggered a process called liquefaction. The ground effectively turned into quicksand, causing buildings to slide or sink directly into the harbour. The disaster, compounded by a tsunami, claimed thousands of lives instantly, while subsequent disease outbreaks decimated the remaining population. A pocket watch recovered from the seafloor in the 1960s remains a silent witness to the exact moment the city collapsed.
Following the catastrophe, the town struggled to recover, hampered by recurring fires, hurricanes, and the rise of nearby Kingston. While the British later established a significant Royal Naval Dockyard there, the site’s commercial importance faded. However, the very disaster that destroyed the city preserved it for history. Underwater archaeological investigations, such as those by Texas A&M University, have recovered remarkably intact organic materials from the submerged ruins. These findings allow researchers to reconstruct the daily routines of a 17th-century colonial port in unprecedented detail, cementing its legacy as the City That Sank.
