York has been defended by walls since Roman times, and this walk strings together six places around them: the Multangular Tower, York Minster, Clifford's Tower, Micklegate Bar, the Shambles and Walmgate Bar.
Each stop is a moment in the city's story, from a Roman fort built around 71 AD to a siege in 1644.
A short walk from the Rialto Bridge to Piazza San Marco packs in Shylock's Rialto, a clock tower from a Bond film, the basilica that holds Saint Mark, Galileo's telescope demonstration and Casanova's roof-top escape from the Doge's Palace.
Six stops lead from the Rialto to the Doge's Palace, each tied to a story: Shakespeare, Moonraker, the legend of Saint Mark, Galileo, Casanova and A Little Romance. The film links are screen fiction, not history.
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.
Nelson Mandela's life runs from a Mbashe River village to the lawns of the Union Buildings in Pretoria, with stops at Fort Hare, Liliesleaf Farm in Rivonia, Robben Island and Victor Verster Prison along the way.
The route follows him from his birth in Mvezo on 18 July 1918 through student days, underground work, years in prison and his inauguration as South Africa's first democratically elected president on 10 May 1994. Most stops can be visited; the pins at Mvezo and Qunu mark the villages, not a single building.
The first transcontinental railroad began at the Sacramento waterfront in 1863, climbed through Dutch Flat and Donner Pass, and ended at Promontory Summit, Utah, where the Golden Spike was driven on 10 May 1869.
The route follows the Central Pacific's eastward build from California: the groundbreaking, Judah's Sierra survey, the granite labour of Chinese workers and the final ceremony. Some stops are approximate.
Bonnie and Clyde's two-year run took them from Eastham prison farm in Texas through a Joplin shootout, the Red Crown Tourist Court in Missouri and Dexfield Park in Iowa, to a roadside ambush near Gibsland, Louisiana.
This route follows the real trail in order, from Clyde Barrow's prison years to the morning of 23 May 1934 and his burial in Dallas. Some spots are only approximately known, and each says so.
Wyatt Earp's story runs from the Long Branch Saloon in Dodge City, Kansas, to the Oriental Saloon, the lot beside Fly's and Boothill Graveyard in Tombstone, Arizona, and on to the railroad tracks of Tucson.
It follows the lawman from his 1878 job as a Dodge City assistant marshal through the Gunfight at the O.K. Corral on 26 October 1881 to the killings that followed in 1882. Exact buildings are uncertain for several stops, and those pins are marked approximate.
Babur, born in Andijan in 1483, fought his way from Samarkand and Kabul to Panipat and Agra and founded the Mughal line that later gave the world the Taj Mahal. The route crosses Uzbekistan, Afghanistan and India.
It follows his conquests and his gardens, and ends at the Taj Mahal, whose charbagh garden follows the pattern Babur introduced. Chauburji's identification as his first tomb is disputed.
Empress Elisabeth of Austria, known as Sisi, grew up at Possenhofen Castle in Bavaria, married in Vienna's Augustinerkirche and died in Geneva in 1898. Her life runs from a lakeside summer home to a hotel on Lake Geneva.
The route follows her through Bad Ischl, Gödöllő, the Achilleion on Corfu and the Imperial Crypt in Vienna. The Gödöllő stop has no verified pin.
Antoni Gaudí's Barcelona runs from Casa Vicens in Gràcia and Palau Güell in El Raval to Park Güell, Casa Batlló, La Pedrera and the Sagrada Família.
Follow the architect from his first major house in 1883 to the tram accident of June 1926. Most stops are open to visitors; the exact spot of the accident is approximate.
Vincent van Gogh was born in Zundert in the Dutch province of North Brabant and died in Auvers-sur-Oise. In between came Nuenen, Antwerp, the Yellow House in Arles and the asylum at Saint-Rémy.
This route follows six places in his life, from the birthplace on the Markt to the attic room at the Auberge Ravoux. Some are gone or only approximate, and each stop says so.
Mozart's life runs from a Salzburg birthplace on Getreidegasse and the cathedral font where he was baptized, through the Figaro House and Stephansdom in Vienna, to the Estates Theatre in Prague where Don Giovanni premiered in 1787.
Six stops follow him from his birth in 1756 to his funeral and burial in Vienna in 1791, and most of them can still be visited.
The Medici ruled Florence from Palazzo Vecchio, Palazzo Medici Riccardi, the Uffizi and the Pitti Palace, and plotters struck at them in the Duomo in 1478. This route follows the family from Cosimo's cell in 1435 to Vasari's private corridor of 1564.
Seven stops, all in the old centre and almost all open to visitors, show how a banking family turned into a ducal court, and how they left offices, tombs and a museum behind.
Leonardo da Vinci's life runs from Vinci, where he was born in 1452, through Milan, Florence and Rome to Amboise in France, where he died in 1519 and was buried at the château.
The route follows six places tied to his life: the Museo Leonardiano in Vinci, Santa Maria delle Grazie in Milan, Florence's Palazzo Vecchio, the Belvedere Courtyard in Rome, Clos Lucé and the Château d'Amboise. Where his remains lie today is only presumed.
The Cathar story runs through Béziers, Carcassonne and Montségur: six places in southern France where the Albigensian Crusade of 1209 to 1255 left its mark.
The route starts with the fall of Béziers and Carcassonne in 1209, continues through the castles of Lastours and the well of Minerve, and ends at Montségur and Quéribus, the last strongholds. Several stops are ruins or later rebuilds, so what you see is not always the medieval Cathar castle.
In June 1791 Louis XVI and his family fled the Tuileries Palace in Paris for the fortress of Montmédy, only to be stopped at Varennes-en-Argonne after being recognised at Sainte-Menehould.
This route marks the royal coach's stops from the palace to Varennes, the citadel it never reached, and the way back through Châlons to a silent Paris. Several stops are approximate, because the sources do not name exact buildings.
Richard III's story runs from Middleham Castle in Yorkshire to Bosworth Field, where he died in 1485, and on to Leicester, where his grave was found under a car park in 2012.
The route follows his childhood at Middleham, the battle of Tewkesbury, the princes at the Tower of London, his last charge at Bosworth, and the Greyfriars dig and cathedral tomb in Leicester. The exact Bosworth battlefield is still debated.
Mary, Queen of Scots was born at Linlithgow Palace in 1542 and beheaded at Fotheringhay Castle in 1587, with Holyroodhouse, Loch Leven and Carlisle along the way. Her life runs from a royal cradle to a prison and a scaffold.
The route follows seven places: her birthplace, the Edinburgh palace where Rizzio was murdered, the island prison she escaped, the battlefield at Langside, two English prisons and the site of her execution. Fotheringhay Castle was demolished, so only earthworks remain.
The route from the Varangians to the Greeks ran from Staraya Ladoga by the Volkhov and Lake Ilmen, down the Dnieper past Kyiv and Khortytsia, to Berezan and the Golden Horn of Constantinople. It is the river road that linked the Baltic to the Byzantine capital.
The six stops follow Rurik, Oleg and Sviatoslav along it, through the Primary Chronicle's tales of 862, 882, 907 and 972. Several accounts are legend-tinged, and the stops are not in strict date order because they follow the river.
Miyamoto Musashi, Japan's most famous swordsman, moves through this route from the Sekigahara campaign of 1600 to the duel on Ganryū Island, Osaka Castle, Kumamoto Castle and the cave of Reigandō, where he wrote The Book of Five Rings.
The route follows the biography stop by stop, from a village birthplace that sources place in two provinces to the cave where he spent his last years. Several details, including his role at Sekigahara and Osaka, are debated or rest on later accounts.
Agatha Christie's Devon runs from Burgh Island, the model for Soldier Island in And Then There Were None, to Churston, Dittisham and her own Greenway estate on the River Dart.
The route follows five stops through The A.B.C. Murders, And Then There Were None, Five Little Pigs, Towards Zero and Dead Man's Folly. Two stops share the Greenway pin, and Nasse House is fictional.
Beatrix Potter's tales are set in the real Lake District: Mr McGregor's garden at Lingholm near Derwentwater, Owl Island on St Herbert's Island, Mrs Tiggy-Winkle's home on Catbells, and the village and farm of Near Sawrey, including Hill Top.
The route follows five places from Peter Rabbit in 1901 to the Hill Top tales of 1907 and 1908, moving from the shores of Derwentwater to the house Potter bought in 1905. Some pins mark an area, not a single spot.
Hans Christian Andersen's Denmark runs from a cobbler's house in Odense to the Royal Danish Theatre, the colourful quay of Nyhavn and the bronze Little Mermaid on Copenhagen's Langelinie.
The route follows the shoemaker's son who left Odense at 14 to become an actor; a theatre colleague told him he was a poet instead. Two Odense houses, three Copenhagen landmarks and a ride at Tivoli show where his life and his stories touch the map. The birthplace house is traditionally identified, not proven.
