In August 1492 three small ships slipped down the Río Tinto from Palos with a plan to reach the Indies by sailing west. By mid-March 1493 Columbus was back in Palos without his flagship, which had been wrecked off Hispaniola, but with captives, samples of gold and plants unknown in Europe.
The route follows the voyage in order: the friary where the plan found friends, a stopover in the Canaries, the first landfall in the Bahamas, the wrecked flagship and the fort of La Navidad, a storm-driven stop in Lisbon, the return to Palos and the report to the monarchs in Barcelona. The landfall island and the fort site are both debated, and the pins say so.
In 1271 a seventeen-year-old Venetian set out with his father and uncle for the court of Kublai Khan and did not come home for 24 years. Years later, in a Genoese prison, he dictated what he had seen to a fellow inmate, and The Travels of Marco Polo was the result.
The route follows the book from Venice and Acre to the Persian Gulf, across the Pamir highlands and the desert to Kublai's summer and winter capitals, south to Hangzhou and the port of Zayton, and home again. Some of the roads are reconstructed by scholars, and Polo sometimes exaggerates, so each stop notes where the evidence is thin.
On 20 September 1519 five ships and about 270 men sailed from Spain to find a western sea road to the Spice Islands. Magellan died in the Philippines, but Juan Sebastián Elcano brought the Victoria home three years later with eighteen survivors and 26 tons of spices, having sailed all the way around the world.
The route follows the voyage from the mouth of the Guadalquivir past Port St. Julian, through the strait and across the Pacific to the Moluccas, then home past the Cape of Good Hope. Anchorages are often unrecorded, so most pins mark the nearest known place; the dates come from Pigafetta's journal and modern accounts.
