Esfera conmemorativa de la Primera Vuelta al Mundo

The Esfera conmemorativa de la Primera Vuelta al Mundo in Seville is a steel armillary sphere standing on the right bank of the Guadalquivir River, in the Los Remedios district, near the Delicias bridge and Plaza de Cuba. Also known as "Milla Cero" (Kilometre Zero), the monument marks the historic spot from which a fleet of five ships set sail on 10 August 1519 under Ferdinand Magellan, and to which, three years later under Juan Sebastián Elcano, the expedition returned after completing history's first circumnavigation of the globe.

Where exactly does the monument stand, and why here?

In the 16th century, the Guadalquivir was Seville's gateway to the world — ships departed downriver toward the port of Sanlúcar de Barrameda before heading out to the open ocean. The former waterfront known as Puerto de las Mulas, close to today's Los Remedios, was the point from which Magellan's fleet cast off on 10 August 1519. Three years later, on 6 September 1522, the sole surviving ship, the Victoria, commanded by Elcano, returned to the same city, closing the loop of the first voyage around the world. It is at this symbolic meeting point of departure and return that the sphere now stands.

What does the sphere represent, and where does its shape come from?

The monument is a large metal structure shaped as an armillary sphere — a historic astronomical and geographical instrument made of rings representing the movement of celestial bodies around the Earth. The form is deliberate: it draws on the armillary sphere depicted on the title page of "Suma de Geographía," a treatise by Martín Fernández de Enciso published in Seville in 1519, the very year the expedition set out. The book was one of the earliest geographical treatises produced in Spain after the discovery of the Americas and served as a practical reference for navigators of the age of exploration.

Why does this site matter to the history of seafaring?

The Magellan-Elcano expedition was unprecedented: of five ships and roughly 240 crew members, only one vessel and a handful of survivors made it back to Seville, yet their achievement permanently reshaped how the world understood its own geography. For the first time, it was proven in practice that the Earth was round and could be circled by sea, linking the Atlantic and Pacific oceans into a single navigable route. Seville, as the expedition's home port and seat of the Casa de Contratación (the Crown's trade and exploration office), played a central organisational and financial role, making the city a fitting place to commemorate the feat.

How does the sphere fit into Seville's wider trail of memory?

The Milla Cero monument is not the only site in Seville recalling the first circumnavigation. The city also holds a monument to Juan Sebastián Elcano near the Delicias bridge, a bust of Ferdinand Magellan on Plaza de España, and gardens named after him. The armillary sphere, however, marks the most literal point of reference — the actual site of departure and return — setting it apart from monuments dedicated to individual figures.

Frequently Asked Questions

Where exactly does the Esfera conmemorativa de la Primera Vuelta al Mundo stand? On the right bank of the Guadalquivir, in the Los Remedios district near Plaza de Cuba and the Delicias bridge, on the site of the former Puerto de las Mulas waterfront used in 1519.

Why is the monument shaped like a sphere rather than, say, a ship or a statue? Because it references the geography and navigation of the era — its form is based on the armillary sphere shown on the title page of "Suma de Geographía" by Martín Fernández de Enciso, published in Seville in 1519.

What is the connection between this site and the Magellan-Elcano expedition? It marks the symbolic starting point (10 August 1519) and closing point (6 September 1522) of the first circumnavigation of the globe — hence the name "Milla Cero," or "Kilometre Zero," of the voyage.

Are there other sites in Seville related to this expedition? Yes — a monument to Elcano near the Delicias bridge, a bust of Magellan on Plaza de España, and the Magallanes Gardens, which together with the sphere form a trail commemorating the first voyage around the world.
