The obvious, but critical, point about the capital in which the Act of Longitude was passed was its size. It was a tiny fraction of modern London, still focused almost entirely around the City.
During the course of the 18th century, London expanded rapidly to incorporate new developments like Mayfair and Bloomsbury. But Belgravia, Chelsea, Fulham and Hammersmith remained well outside the city limits.
The 18th Century was good to the growing city. London became healthier, wealthier and considerably grander than the old wooden town that had gone up in flames in 1666. The new St Paul's was completed in 1708; Westminster Bridge - only the city's second after London Bridge - was completed in 1750.
The 18th Century brought newspapers and a regular police force to London: the first daily was published in Fleet Street in 1702; the Bow Street Runners were founded in 1749 by the author Henry Fielding. Coffee houses became popular, and began hosting stock and commodity traders and auctions, leading eventually to the formation of Christie's, Sotheby's and the London Stock Exchange.
The Isles of Scilly are made up of six inhabited islands and a scattering of rocky islets, 28 miles from Land’s End in Cornwall. Today, the islands are a favourite tourist destination, enjoying warmer weather than the rest of the UK. One of the islands, Tresco, boasts the world-famous sub-tropical Abbey Garden.
After the earthquake, the refugees moved to the mainland side of the Harbour and founded Kingston, although the new town did not replace Port Royal as commercial centre until the latter was further destroyed by fire in 1703. Following the earthquake, the capital was moved to Spanish Town, but frequent attempts were made to rebuild Port Royal, each of them frustrated by hurricanes, fire or flooding. Another earthquake in 1907 finished off the city, and today just 2,000 people live in Port Royal, while across the water Kingston is the capital with a population of 650,000. Port Royal features in the Pirates of the Caribbean films, as well as James Michener’s book, Caribbean.
