Bridgetown

Rebuilt in 1789 after hurricane damage, and promoted to a cathedral in 1825 when the Anglican Diocese of Barbados was created, it's a pleasant coral-stone structure, highlights include the tower, 17th-century font, stain glass windows, and chapel. Sir Grantley Adams, the island's first Premier, is buried in the graveyard.

Exhibiting currency and exchange, with sections on the Freemasons and an old classroom.

Anglican church built in 1827 but there's been a church on this site since 1630. The elaborate font was a gift from a Jewish merchant in 1863.

This was built in 1654, so it's one of the oldest in the Americas. Jewish refugees arrived from Brazil in that era - they knew a lot about sugar production and helped the Barbados cane industry get started. The synagogue was wrecked by a hurricane in 1831, rebuilt, but fell into disuse and was deconsecrated in 1929. It was on the verge of being demolished, but refurbished and services resumed in the late 20th century, though it's now primarily a museum. Excavation in 2008 revealed a 17th-century mikveh or ritual cleansing bath.

Neo-Gothic government buildings, normally open to the public when parliament is in session, but the public gallery and museum are closed for renovation.

The official residence of the Barbados prime minister is occasionally open as an events venue.

The only overseas trip George Washington ever made was to Barbados, in 1751 aged 19, accompanying his older half-brother Lawrence who was seriously ill with tuberculosis. He stayed several weeks in this plantation-style mansion, fell ill himself with smallpox, but recovered to make his mark on history. His observations of Barbados farming methods, social structure and military defences served him well when he returned to Mount Vernon, Virginia. The ground floor is reconstructed to that period, upstairs is an exhibition on island life over the centuries. The house backs onto that archaeologists' delight, a midden: the island's limestone gullies were long used as trash and dung heaps, so there's a rich mixture down there of Arawak fish-bone artefacts, plastic cups, broken buttons, and Washington's poxy poop. Beneath the house in 2011 were discovered tunnels, a star-burst of long, deep channels radiating from the Savannah, built circa 1820. They're said to be for drainage, but they're excessively elaborate for that simple task, up to 17 feet deep and half a mile long - maybe a work-creation Folly for the post-Napoleonic peace? There's a pleasant cafe.

Housed in the former British Military Prison, this museum covers the emergence from the sea of this coral island, its indigenous peoples, the arrival of Europeans and African slaves, the colonial period, emancipation of the slaves, independence from Britain, and more recent history.
