Port Royal sits at the tip of the Palisadoes, the narrow tombolo that encloses Kingston Harbour from the south. In the second half of the seventeenth century it was the most important English port city in the Caribbean, the wealthiest city in the Americas by some accounts — a place built on the privateering trade, the sugar economy, and the concentration of merchant shipping passing through the western Caribbean. The 1692 earthquake, one of the most destructive seismic events in Caribbean history, dropped an estimated two-thirds of the town into Kingston Harbour in approximately two minutes. The submerged ruins — buildings, streets, and artefacts — lie in 6 to 9 metres of water directly off the current waterfront and are legally protected as an archaeological site under Jamaica's National Heritage Trust. The tidal regime at Port Royal is Caribbean mixed semidiurnal, microtidal: spring range typically 0.5 to 0.7 metres inside the sheltered harbour. The Palisadoes barrier to the south blocks the open Caribbean swell; the water inside Kingston Harbour is generally flat, with tidal current running through the narrow harbour entrance between Port Royal and the southern tip of the airport runway. The entrance current peaks at spring tide and is relevant to small craft navigating the harbour mouth. Above water, Port Royal is a small fishing community of approximately 1,200 people with a working fishing beach, a historic fort (Fort Charles, still standing), the tilted Giddy House (an artillery store whose foundation shifted in the 1692 earthquake, now permanently canted at an angle), the Naval Hospital ruins, and water taxi service to the Kingston waterfront. Fort Charles is one of the oldest English military structures in the Western Hemisphere; the parapet walk has views across the harbour entrance and toward the Blue Mountains. The fortifications were substantially rebuilt after the 1692 earthquake and continued in use into the twentieth century. Fishing from the Port Royal beach and the pier is a daily activity. The harbour entrance, where the tidal current concentrates bait, is productive for snapper and jacks on the incoming flood; dawn and dusk are the primary windows. The water taxis to Kingston run from the main pier throughout the day and provide a practical way to approach the Kingston waterfront from the south, particularly to avoid the road traffic on the Palisadoes highway. The archaeological dive sites at the submerged 1692 town are accessible to licensed dive operators with permits from the National Heritage Trust; recreational dives to the site require going through an authorised operator. The visibility in the harbour is variable — harbour conditions are different from open Caribbean — and the site is a genuinely significant historical location that warrants the care the permitting system requires. For photography, the view from the Palisadoes road approaching Port Royal — the causeway with the harbour to the north and the open Caribbean to the south — gives a sense of the geographic position that made the original port strategically valuable. The Norman Manley International Airport runway runs along the same narrow strip; the aircraft approach is over the harbour, low and close. Tide predictions for Port Royal come from Open-Meteo Marine, a global gridded ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height. The historical record of Port Royal's pre-1692 character is unusually detailed for a seventeenth-century Caribbean town. Contemporary accounts, port records, and the subsequent archaeological excavation of the submerged town have produced a picture of a city with 2,000 buildings, hundreds of taverns, and a concentration of wealth disproportionate to its size. Henry Morgan, the Welsh privateer who became Jamaica's Lieutenant Governor, was one of the more prominent residents. The earthquake that destroyed it was treated by some contemporaries as divine judgment; the immediate rebuilding of the town suggests the inhabitants took a more practical view.
