The Aztec Sun Stone is not in the British Museum. The celebrated carved stone, also called the Calendar Stone or the Stone of the Five Eras, is held by Mexico’s National Museum of Anthropology in Mexico City.
Where the Sun Stone is today
The museum’s official name is the Museo Nacional de Antropología (National Museum of Anthropology). Its collection includes the monumental basalt sculpture, which is displayed in the Mexica gallery. The Mexica were the people who built the imperial centre of Tenochtitlan, now beneath central Mexico City, and are often referred to in English as the Aztecs.
The British Museum does hold important objects from the Americas, including material connected with ancient Mexican cultures, but it does not hold the famous Sun Stone. Online images, catalogue references, or comparisons with other Mesoamerican objects can make the location easy to confuse. For a visit or current display details, check the National Museum of Anthropology’s own information: exhibitions and access arrangements can change.
What the sculpture is
The Sun Stone is a large, circular relief carved from basalt. It is roughly 3.6 metres (about 12 feet) across and weighs around 24 tonnes. Its surface is crowded with carved forms arranged around a central face, concentric bands, and four prominent symbols around the centre. It is among the best-known works of Mexica art, but it was not simply a calendar page carved in stone.
The name “Sun Stone” is a modern label, and interpretations of the monument’s purpose and imagery have developed over time. It is commonly associated with Mexica ideas about time, the sun, and the successive worlds or ages that preceded the present one. Scholars also discuss it in relation to political and religious meanings. Its imagery should not be reduced to a single, universally agreed translation.
How its central imagery works
At the centre is a face commonly identified as Tonatiuh, the sun deity, although some interpretations identify the face with a different being or read it more broadly as a symbol of the sun and cosmic power. The figure extends its tongue, often understood as a sacrificial knife, and holds forms interpreted as human hearts. This imagery connects the monument with Mexica ritual and cosmology, but does not mean every part of the sculpture has one uncontested meaning.
Four square signs surrounding the central face are generally identified as the names of earlier suns or eras in Mexica creation traditions: 4 Jaguar, 4 Wind, 4 Rain, and 4 Water. The centre is associated with the current era, 4 Movement, known in Nahuatl as Nahui Ollin. In accounts recorded after the Spanish conquest, earlier worlds end through different disasters; details and wording vary among sources and retellings.
Other rings contain signs associated with days and calendrical cycles. The Mexica used interlocking ways of reckoning time, including a 260-day ritual calendar and a 365-day solar calendar. Their combination formed a larger cycle. The stone’s carved day signs and numerical forms are part of this calendrical setting, but the monument is not a straightforward chart from which every date or prediction can be read at a glance.
Why it is often called a calendar
“Aztec Calendar Stone” is a familiar alternative name, but it can give the wrong impression. The Sun Stone contains calendrical symbols and expresses ideas about cosmic time; it was not a practical calendar with rows of months and a simple system for tracking each day. Researchers continue to examine its relationship to ritual, political authority, and the sacred landscape of Tenochtitlan.
Nor should the central face and surrounding symbols be treated as a literal picture of a single creation story. Mexica religious ideas were expressed through layered images, and accounts of them survive through sources with different purposes and perspectives. The sculpture is best understood as a major monument combining calendrical, religious, and political significance, rather than as an illustrated textbook.
Discovery and history
The stone was carved in the late fifteenth century, during the Mexica empire. It was found in 1790 during construction work in Mexico City, near the former ceremonial precinct of Tenochtitlan. After its discovery, it was set into a wall of the cathedral, where it remained visible for decades. It was later moved to the National Museum, and it became a defining object in public presentations of Mexico’s pre-Hispanic past.
The monument’s later history matters as much as its carving. Tenochtitlan was conquered by Spanish forces and their Indigenous allies in 1521, and colonial Mexico City grew over the former Mexica capital. The Sun Stone’s discovery in the city made a powerful ancient object visible within a transformed urban landscape. Its current museum setting allows visitors to encounter it alongside other objects from Mexica and wider Mesoamerican history.
Seeing it in person
Visitors can see the original in Mexico City, not London. It is large enough that photographs can obscure its scale: the carved rings and central figure are easier to take in when viewed from a little distance, while closer viewing helps reveal the individual signs. Museum labels and gallery context are useful because many popular diagrams simplify or assign fixed meanings to details that remain debated.
- For the original: look for the National Museum of Anthropology in Mexico City and confirm current visitor information before travelling.
- For study or reference: museum collections and reputable archaeological sources can provide detailed photographs and diagrams.
- For London visitors: the British Museum has its own collections from the Americas, but seeing those objects is not the same as seeing the Sun Stone.
Reproductions, casts, and images may appear in exhibitions or educational materials in different places. A reproduction should not be confused with the original basalt monument. When a listing says “Aztec Sun Stone” without clarifying whether it means an image, a cast, or the ancient sculpture, check the object description and owning institution.

No. The original is in the National Museum of Anthropology in Mexico City.
What is the Aztec Sun Stone also called?
It is also known as the Calendar Stone and the Stone of the Five Eras. “Aztec Calendar Stone” is widely used, although it can imply too simply that the sculpture is a working calendar.

The original is not in London. The British Museum may display other objects from the Americas, but any image or reproduction of the Sun Stone is not the original monument.
What does the face in the middle represent?
It is commonly identified as Tonatiuh, the sun deity, but interpretations differ. The central figure is connected with Mexica ideas about the sun and cosmic order.
How old is the Sun Stone?
It was carved in the late fifteenth century, during the Mexica empire, and was discovered in Mexico City in 1790.

It includes calendar signs and expresses ideas about time, but it is not a simple day-by-day calendar. Its exact purpose and the meaning of some details remain subjects of scholarly interpretation.
