For three centuries London was the place expeditions were funded, argued over, planned, and returned to, which means the people who mapped the poles, crossed Australia, walked into West Africa, and got the first British aeroplanes off the ground nearly all had London addresses. The blue plaques record them at home, in the ordinary interval between attempts. Walk the city with an eye for the blue discs and you pass the Stepney house of the navigator who charted the Pacific, four separate plaques for men who died in Antarctica, the Highgate house where a girl who was refused an education taught herself and later travelled alone through West Africa, and a railway viaduct in Walthamstow where a man assembled a triplane under the arches.
This is a guide to the blue plaques that mark London's explorers, travellers, and aviation pioneers, part of the wider blue plaque scheme that records the city's history house by house.
The Great Navigators
At The Highway in Stepney, a plaque records Captain James Cook, described on it as "the ablest and most renowned Navigator this or any country hath produced". Cook lived in Shadwell in the years before the Pacific voyages that charted New Zealand and the east coast of Australia, mapped the Pacific with an accuracy that stood for a century, and demonstrated that scurvy could be controlled at sea. The plaque marks a modest east London address for a man whose charts changed what the map of the world looked like.
At 56 Fitzroy Street, a plaque marks Captain Matthew Flinders (1774-1814), explorer and navigator, who circumnavigated and charted the coastline of Australia and popularised the name Australia itself. He returned from that voyage by way of six and a half years' detention on Mauritius by the French, reached London in poor health, and died the day after his account of the expedition was published.
At 9 Campden Hill Square, a plaque records John McDouall Stuart (1815-1866), the first explorer to cross Australia from south to north and return, a journey that established the route later followed by the overland telegraph. He lived and died in the house.
Antarctica
No group of plaques in London is quite as sombre as the polar ones, because four of them mark men who did not come home.
At 56 Oakley Street in Chelsea, a plaque records Robert Falcon Scott (1868-1912), Antarctic explorer, who reached the South Pole in January 1912 to find Amundsen had arrived five weeks earlier, and died with his companions on the return march. At Battersea Vicarage, 42 Vicarage Crescent, a plaque marks Edward Adrian Wilson (1872-1912), Antarctic explorer and naturalist, the expedition's doctor and artist, who died in the same tent. And at 307 and 309 Upper Richmond Road in Putney, two plaques record Captain Lawrence Oates (1880-1912), who walked out into the blizzard in the hope of giving the others a chance, in what is probably the most quoted act of self-sacrifice in British exploration.
At 12 Westwood Hill in Sydenham, a plaque marks Sir Ernest Shackleton (1874-1922), whose Endurance expedition failed in its objective and produced instead the greatest survival story of the age: the ship crushed by ice, the crossing to Elephant Island, and the 800-mile open-boat voyage to South Georgia from which he returned having lost nobody. At Connaught Road in Harlesden, a plaque records the polar explorer Victor Hayward, who died on the Ross Sea side of that same expedition, which is a useful corrective, because the Ross Sea party's ordeal, and its three deaths, are usually forgotten in the retelling of Shackleton's escape.
The Arctic has its own plaques. At 2 Eliot Place, Blackheath, one records Sir James Clark Ross (1800-1862), polar explorer, who located the north magnetic pole and led the Antarctic voyage that gave the Ross Sea and Ross Ice Shelf their names. At 4 Lower Addison Gardens in Holland Park, a plaque marks John Rae (1812-1893), the Arctic explorer who mapped much of the northern Canadian coast, learned survival methods from the Inuit rather than dismissing them, and discovered the fate of the lost Franklin expedition. He reported honestly what the Inuit had told him about the men's final weeks, was vilified in Britain for repeating it, and was denied the recognition his contemporaries received. Rae's plaque is among the quietly consequential ones in the Holland Park group.
The Travellers
Two women's plaques mark journeys that were extraordinary for anyone and nearly unthinkable for a Victorian woman travelling alone.
At 22 Southwood Lane in Highgate, a plaque records Mary Kingsley (1862-1900), traveller and ethnologist, who lived there as a child. Denied the education given to her brother, she read her way through her father's library, and after both parents died she went to West Africa, twice, travelling by canoe and on foot through Gabon, collecting fish specimens for the British Museum, climbing Mount Cameroon by a route nobody had used, and returning to argue publicly against the missionary view of African societies.
At 95 Sloane Street, a plaque marks Gertrude Bell (1868-1926), traveller, archaeologist and diplomat, who travelled extensively in Arabia, mapped and excavated across Mesopotamia, and became one of the most influential British officials in the creation of the state of Iraq, as well as the founder of its national museum. Both women appear in the wider story told in our guide to the women's blue plaques of London.
At 2 Richmond Terrace, Whitehall, a plaque records Sir Henry Morton Stanley (1841-1904), explorer and writer, who lived and died there. Stanley is the most famous and the most troubling name in this collection: the man who found Livingstone and traced the course of the Congo, and whose later expeditions, and his role in establishing King Leopold's claim to the Congo, are inseparable from what followed there. And at 15 Buckingham Gate, a plaque marks Wilfrid Scawen Blunt (1840-1922), diplomat, poet and traveller, who became a vocal anti-imperialist and was imprisoned for his support of Irish home rule.
Mountaineering gets one entry. At 82 Waldegrave Road in Teddington, a plaque records Edward Whymper (1840-1911), the mountaineer who made the first ascent of the Matterhorn in 1865, on a descent that killed four of his party and made him famous and haunted in roughly equal measure.
Aviation: From a Railway Viaduct to the Jet Age
British aviation began, more or less literally, under a railway bridge. At the Walthamstow Marshes railway viaduct, plaques record that A. V. Roe (1877-1958) assembled his AVRO No. 1 triplane under the arches, and made the first all-British powered flight there in July 1909. The company he founded, Avro, went on to build the Lancaster bomber and the Vulcan.
The other founders of the industry are marked across west London. At 32 Baron's Court Road, a plaque records Sir Geoffrey de Havilland (1882-1965), aircraft designer, whose company produced the Mosquito and then the Comet, the world's first commercial jet airliner. At 46 Green Street in Mayfair, a plaque marks Sir Thomas Sopwith (1888-1989), aviator and aircraft manufacturer, whose Camel was the most successful British fighter of the First World War, and who lived to be 101. At 18 Grosvenor Square, a plaque records Sir Frederick Handley Page (1885-1962), aircraft designer and manufacturer, and at 499 Hale End Road in Highams Park, one marks Sir George Edwards (1908-2003), the designer behind the Viscount, the VC10, and Concorde.
The fliers have their own plaques. At 32 Aberdeen Place in St John's Wood, a plaque records Guy Gibson VC (1918-1944), the pilot who led the Dambusters raid and was killed the following year. At 5 Petersham Mews, a plaque marks Sir Douglas Bader (1910-1982), the RAF fighter pilot who lost both legs in a pre-war crash, talked his way back into flying, and led a squadron through the Battle of Britain. At 139 Hendon Way, a plaque records Wing Commander J. R. D. "Bob" Braham (1920-1974), one of the most decorated night-fighter pilots of the war, who lived there as a boy.
Two plaques mark men whose flying was one part of a much larger life. At 22 Philbeach Gardens in Earls Court, a plaque records Arthur Wint (1920-1992), described as RAF pilot, doctor, diplomat and Olympic gold medallist: a Jamaican who volunteered for the RAF, stayed to study medicine, won the 400 metres in London in 1948, and later served as Jamaica's High Commissioner. And at Jackson's Lane in Highgate, a plaque marks Cy Grant (1919-2010), the Guyanese RAF navigator who was shot down over the Netherlands and held as a prisoner of war, and who afterwards became a pioneering Black actor, musician, writer, and activist in Britain.
Why the Expeditions Started in London
The pattern is straightforward once you see it. London held the money, the institutions, and the argument. The Royal Geographical Society, the Admiralty, the learned societies, the newspapers who would pay for the story, and the wealthy backers who funded the attempts were all within a couple of miles of each other, so anyone planning a serious expedition had to be here to raise it. The same was true of the aviation pioneers a century later, though for a different reason: they needed flat, empty ground on the edge of a city with engineering workshops and investors in it, which is why the industry began on the marshes and airfields of the London fringe, at Walthamstow, Hendon, Brooklands, and Croydon.
There is a sadder pattern in the polar plaques in particular. Several of them mark family homes rather than the addresses of men who lived long enough to settle anywhere: Scott, Wilson, and Oates all have plaques in London and graves in Antarctica.
An Explorers' London Walk
The plaques do not cluster tidily, which suits a set of short journeys. The Antarctic trail is the most affecting: Scott on Oakley Street in Chelsea, Wilson at Battersea Vicarage just across the river, and Oates in Putney, all reachable in an afternoon, with Shackleton in Sydenham as a separate trip. West London gathers the aviators, with de Havilland in Baron's Court, Sopwith on Green Street, and Bader in Petersham Mews, near the Kensington plaques covered in our guide to Kensington's blue plaques.
North London offers Mary Kingsley in Highgate and Cy Grant a short walk away on Jackson's Lane, and the Walthamstow Marshes viaduct is worth the trip on its own: standing under the arches where the first all-British powered flight was assembled is a better aviation monument than most museums manage. If you want to find these plaques as you walk, and keep a record of the ones you have visited, Legacy maps every blue plaque in London, turning a day of exploring into a collection you build over time. These are the plaques of people who left, which makes the ordinary London houses they left from oddly moving to stand in front of.
