Giovanni da Verrazzano sailed for Francis I of France in 1524 in search of a westward route to Asia. His voyage explored a long stretch of the Atlantic coast of North America and produced one of the earliest detailed European descriptions of the region after the Norse and Cabot voyages.
Verrazzano crossed the Atlantic aboard Dauphine and reached the coast in the region of the present-day Carolinas.
The expedition sailed north along the coast and entered what is now New York Harbor, observing the large estuary and surrounding geography.
Verrazzano continued toward New England and Atlantic Canada before returning to France.
A letter attributed to Verrazzano and addressed to Francis I describes the voyage and encounters with Indigenous communities. As with all exploration narratives, the author’s European assumptions shape the descriptions.
The expedition did not find a passage through North America. Some early maps, influenced by limited coastal observation, mistakenly represented narrow continental widths or imagined nearby western seas.
Later tradition connects Verrazzano with additional voyages, including a final voyage on which he died, but details vary between sources.
For TransitSatellite, the 1524 route should be anchored to well-supported coastal regions while avoiding invented landings at every place named in later commemorative geography.
