Nelson's Dockyard occupies a natural harbor on the southern coast of Antigua that served the British Royal Navy from 1725 through 1889. The complex was named for Vice Admiral Horatio Nelson, who commanded the naval station from 1784 to 1787. The site contains more than fifteen restored buildings including officers' quarters, a copper and lumber store, and sail lofts that now function as a working marina, museum, and hotel. The National Parks Authority manages the property, which gained UNESCO World Heritage designation as part of the Antigua Naval Dockyard and Related Archaeological Sites in 2016. The Georgian naval architecture remains largely intact, making this the only continuously working Georgian dockyard in existence. Visitors walk on original stone pathways and examine naval artifacts including cannons, anchors, and ship's hardware displayed in the Admiral's House Museum.
Shirley Heights sits on a promontory 146 meters above sea level, directly overlooking English Harbour and Falmouth Harbour. The British military began constructing fortifications here in the 1780s to protect the strategic anchorage below. Stone ruins include the signal station, military cemetery with marked graves from the 1780s, gunpowder magazine, and officers' quarters. The lookout point provides views across the southern coastline of Antigua and on clear days southwest to the French island of Guadeloupe, 60 kilometers distant. Sunday afternoon gatherings at the restored restaurant area feature steel pan bands and reggae music, drawing both residents and visitors. The site connects to Nelson's Dockyard through a hiking trail that descends through dry forest.
Barbuda's Frigate Bird Sanctuary covers approximately 6.5 square kilometers of mangrove wetland within Codrington Lagoon on the western side of the island. The colony supports more than 5,000 nesting pairs of magnificent frigate birds, representing one of the largest breeding populations of the species in the Caribbean. Male frigate birds inflate their red throat pouches during courtship displays visible from September through April. Boat tours depart from Codrington village and navigate through mangrove channels to reach viewing areas where birds nest in low branches. Brown pelicans, cormorants, and several heron species also nest within the lagoon system. Hurricane Irma passed directly over Barbuda in September 2017 as a Category 5 storm, damaging approximately ninety percent of structures on the island and forcing evacuation of the entire human population. The frigate bird colony survived with losses primarily to nesting trees rather than adult birds.
Betty's Hope preserves the stone remains of a sugar plantation that operated from 1650 until 1944. The estate belonged to the Codrington family for much than two hundred years. Two windmill towers remain standing, with one fully restored to working condition in the 1990s including functional grinding machinery powered by canvas sails. The second tower stands as a stabilized ruin. Archaeological evidence shows the original estate covered more than 400 hectares and enslaved over 300 people at peak production. Interpretive panels mark the locations of boiling houses, curing houses, and enslaved workers' quarters identified through excavation. The Museum of Antigua and Barbuda provided historical research for site interpretation. The windmill mechanism demonstrates the process of crushing sugarcane to extract juice, which was then boiled in copper kettles to crystallize raw sugar for export to Britain.
Devil's Bridge formed through wave action eroding soft limestone on the eastern Atlantic coast of Antigua. The natural arch spans approximately 10 meters and stands above blowholes where incoming waves force water upward through narrow rock channels. Spray reaches heights of 15 meters during heavy surf. Arawak and Carib peoples considered this coastline sacred. During the slavery period, oral history records this location as a site where enslaved people chose death over bondage by jumping from the cliffs. No formal memorial marks the site, though local accounts preserve these events in community memory. The area surrounding the bridge contains tide pools visible at low water and walking paths through coastal scrubland.
St. John's Cathedral occupies a prominent position at the highest point of the capital city. The Anglican church traces its congregation to 1681, though the current structure dates to 1845. Previous buildings on the site were destroyed by earthquakes in 1683 and 1745. The architect designed the church with baroque towers and enclosed the interior walls with pitch pine to protect against hurricane winds and future seismic activity. The south tower holds a clock mechanism installed in 1847. Both towers feature white limestone quoins contrasting with grey stone walls. The interior contains carved wooden pews and memorials to British colonial officials and military officers. The cathedral grounds include a cemetery with grave markers from the eighteenth century.
Dow's Hill Interpretation Centre presents a multimedia exhibition on Antiguan history through pre-Columbian settlement, European colonization, the plantation economy, emancipation, and independence. The center occupies the site of a former British military lookout above English Harbour. A 15-minute film uses narration and historical illustrations to document the sugar plantation system and the lives of enslaved Africans who worked the estates. Physical exhibits include Arawak pottery fragments, colonial-era tools, and reproduction period maps. The observation deck provides views across the harbor to Guadeloupe. The National Parks Authority operates the facility as part of the Nelson's Dockyard complex.
