Isabella Bird's 1873 ride through Colorado, told in A Lady's Life in the Rocky Mountains, runs from Greeley and Fort Collins to Estes Park, Longs Peak and Manitou Springs. She lived out of doors and on horseback, and climbed a 14,700-foot peak with the guide Rocky Mountain Jim.
Six stops follow her letters from the Plains into the mountains and on to Colorado Springs. Most pins mark towns, because her letters rarely name exact buildings.
Florence's Renaissance is packed into a few streets: the Duomo and Brunelleschi's dome, the Medici palace, Piazza della Signoria, the Uffizi and the Ponte Vecchio. Each stop here ties one building to a dated event, from a dome competition in 1418 to Michelangelo's David arriving at the Accademia in 1873.
The walk follows the buildings in date order, from the cathedral to the Accademia, and every stop can be visited. Dates mark the event at each place, not a single journey.
St Petersburg's history can be walked in an afternoon: from the Peter and Paul Fortress, where the city was founded in 1703, past Kazan Cathedral on Nevsky Prospect to Senate Square, Palace Square and the cruiser Aurora on the Neva.
Seven stops follow the city from its foundation through the Decembrist revolt of 1825, the assassination of Alexander II, Bloody Sunday in 1905 and the events of October 1917. The stops zigzag across the centre, so the pins are markers rather than a single line.
Bridget Jones's Diary is set and filmed around Borough Market in south London, with Shad Thames, the Royal Courts of Justice and Cornhill on the way. The film moves Bridget from Holland Park to a flat above the Globe pub, where the story begins.
This route follows the film's story through eight London and country locations: the book launch at the ICA, the first date at Shad Thames, the mini-break at Stoke Park, the anniversary party at Syon House and the snowy finale. The film was shot over six weeks in and around London in 2000.
On 6 August 1945 an atomic bomb was dropped on Hiroshima; three days later, another on Nagasaki. This route follows the two days on the ground, from the bridge that served as the aiming point to the places that survived or were rebuilt.
It starts in Hiroshima at Aioi Bridge, the hypocenter and the Dome, then moves to Nagasaki's hypocenter, cathedral and shrine, and ends with the two museums and parks built in 1955. Death tolls are estimates and are given as the ranges researchers publish.
On 10 November 1871, on the shore of Lake Tanganyika, the journalist Henry M. Stanley took off his hat in front of a crowd and said, as he tells it in his own book, "Dr. Livingstone, I presume?" The explorer many thought dead had been found, after nearly eight months on the road from the coast.
The route follows Stanley's account, How I Found Livingstone, over eight stops: from Zanzibar and Bagamoyo through Mpwapwa, Tabora and the Malagarasi to Ujiji, then up the lake to Mugere and back to the parting at Tabora. Stanley's camps are rarely identifiable today, so every pin is approximate.
A chance meeting at the Criterion Bar sends an army doctor just back from Afghanistan to a laboratory at St Bartholomew's Hospital, where a stranger grips his hand and observes: "You have been in Afghanistan, I perceive." Within days Dr Watson has moved into 221B Baker Street, the address where many of the stories begin, and off runs the canon: four novels and 56 short stories, all but one set between 1880 and 1914.
This route walks Holmes's London in the order the stories appeared: the Criterion where Watson met Stamford, the hospital of the famous first deduction, the Baker Street rooms that did not exist when Doyle wrote and are now a museum, Scotland Yard's Victorian headquarters on the Embankment, a society church where a bride vanishes, a silent club on Pall Mall, and the Underground station where a body fell from a train roof.
The Boshin War ran from Kyoto to Hakodate in eighteen months: the battlefield at Toba, Edo Castle, the hill of Ueno, Aizu's castle and Goryōkaku. In January 1868 the young emperor was declared ruler in fact as well as name, ending more than 250 years of Tokugawa rule, and the last shogun's supporters fought on until a breakaway republic made its last stand.
The route follows that war in six places, all of them visitable: the battlefield at Toba, Edo Castle, the hill of Ueno, Aizu's castle and the hill where its teenage soldiers died, and Goryōkaku. Dates are given in the Western calendar, converted from the Japanese lunar dates used at the time.
