Explorer Christopher Columbus arrives back in Lisbon, Portugal, aboard his ship Niña from his voyage to what are now The Bahamas and other islands in the Caribbean.

Christopher Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas. His expeditions were the first known European contact with the Caribbean and Central and South America.

Lisbon is the capital and largest city of Portugal, with an estimated population of 575,739, as of 2024, within its administrative limits and 3,028,000 within the metropolis, as of 2025. Lisbon is mainland Europe's westernmost capital city, and the only one along the Atlantic coast, the others being on islands. The city lies in the western portion of the Iberian Peninsula, on the northern shore of the River Tagus. The western portion of its metro area, the Portuguese Riviera, hosts the westernmost point of Continental Europe, culminating at Cabo da Roca.

La Niña was one of the three Spanish ships used by Italian explorer Christopher Columbus in his first voyage to the West Indies in 1492. As was tradition for Spanish ships of the day, she bore a female saint's name, Santa Clara. However, she was commonly referred to by her nickname, La Niña, which was probably a pun on the name of her owner, Juan Niño of Moguer. She was a standard caravel-type vessel.

Between 1492 and 1504, the Italian explorer and navigator Christopher Columbus led four transatlantic maritime expeditions in the name of the Catholic Monarchs of Spain to the Caribbean and to Central and South America. These voyages led to Europeans learning about the New World. This breakthrough inaugurated the period known in Europe as the Age of Exploration, which saw the colonization of the Americas, a related biological exchange, and trans-Atlantic trade. These events, the effects and consequences of which persist to the present, are often cited as the beginning of the modern era.
