Chichen Itza, Mexico: where is it located?
Chichen Itza is a pre-Columbian Maya city on Mexico’s Yucatán Peninsula. You will find it between Valladolid and Mérida. If you are tracing it on a map, those two towns are your anchors.
UNESCO says the city grew up near two natural sinkholes, called cenotes, that gave access to groundwater. That water helps explain why people settled here.
Chichen Itza meaning and pronunciation
The name comes from the Maya language. It means roughly “at the mouth of the well of the Itza.” The well is the clue: the name points straight at the water.
Say it the Spanish way: [tʃiˈtʃen iˈtsa]. Stress the last syllable of each word. So it is chee-CHEN ee-TSA, not chee-chen IT-za.
Chichen Itza pyramid: what is the Kukulkan Pyramid?
The city’s famous pyramid is the temple of Kukulkan, the Maya feathered serpent god. It is also called El Castillo, Spanish for “the castle.”
The whole structure stands about 30 metres tall. That figure includes a temple of about 6 metres on top. Each side of its square base measures about 55.3 metres.
The body rises in nine stepped levels. A staircase climbs each of the four faces.
Timeline

- AD 998: The latest known dated inscription, on the Osario Temple.
- 1930s: An older pyramid was found inside El Castillo.
- 1960s–1970s: Publications by Rivard and Arochi increased public awareness of the descending serpent.
- 1972: Mexico’s federal monuments law, on which the site’s protection rests, dates from this year.
- 1986: A presidential decree declared Chichen Itza an archaeological monument.
- 1988: UNESCO added it to the World Heritage List.
- 16 November 2016: UNAM and INAH announced a second inner pyramid, found with electrical tomography.
- 15–29 March 2017: A photo series documented the light pattern around the equinox.
- 2018: Casares Contreras published a calendar-based, Venus-linked reading of the light effect.
The secret of the serpent: how the shadow works
Near the equinoxes, the sun sets behind the stepped body of the pyramid. The shadows of the nine platforms fall across the balustrade of the north staircase. They bring out seven triangles of light there.
At the foot of that staircase sits a stone serpent head. The light-and-shadow pattern on the stairs joins with that head. Together they give the look of a snake coming down the pyramid.
Think of the way a window blind throws a zigzag of light across a kitchen wall in the late afternoon. The pattern is just sun, edges and angle. Here the edges are the nine platforms, and the wall is a staircase.
It is not only one day
Many visitors expect a single magic moment. The evidence says otherwise. The Exploratorium states that the serpent effect can be seen about a week before and after the spring and autumn equinoxes.
A photo series makes the same point. Miguel Ángel Cab Uicab took pictures at five-minute intervals from 15 to 29 March 2017. They showed that the snake-like pattern stayed largely similar across those 15 days.
So if you plan a trip, you do not need to stand there on the exact equinox. The window is wider than the date.
Was it built on purpose?
This is the real argument. Nobody can answer it with certainty.
The Exploratorium counts the large serpent heads at the base of the stairs among the signs that the light effect was designed. But it stresses that the builders’ intent cannot be known for sure.
Archaeoastronomers Ivan Šprajc and Pedro Francisco Sánchez Nava disagree on one point. The seven triangles appear before and after the equinox. In their view, the pattern cannot be a marker that fixes the equinox day exactly.
A third reading comes from INAH researcher Orlando J. Casares Contreras. In a 2018 article he proposed linking the light event to calendar symbolism and to observation of the synodic periods of Venus.
The modern fame of the descent is fairly recent. It grew after descriptions published by Jean-Jacques Rivard and Luis Arochi in the 1960s and 1970s.
A calendar in stone
The numbers on the stairs are easy to check. Each of the four staircases has 91 steps. Four times 91 is 364. Add the top platform and you reach 365, the number of days in a solar year.
That count works like the days printed on a wall calendar. You can verify it with your own feet if you climb the steps and count.
Details you won’t find in guidebooks
- A smaller pyramid inside. In the 1930s, an older pyramid was found inside El Castillo. It has a single staircase on the north. The temple on top held a red jaguar and a Chac Mool sculpture.
- A second one inside that. On 16 November 2016, UNAM and INAH researchers announced that three-dimensional electrical tomography had found an even older structure inside the known inner pyramid. It is about 10 metres tall.
- Water underneath. The same UNAM announcement reported a water-filled cavity, a cenote, beneath the Kukulkan Pyramid.
- The bird in the stairs. Stand in front of the north-northeast staircase and clap. The sound bounces off the steps and returns as an echo like the call of a quetzal bird.
- A city of roads. According to Smithsonian, more than 20 building groups at Chichen Itza are linked by 75 roads.
What else is at Chichen Itza?
The pyramid is not the only reason to visit. The city holds the largest ball court in Mesoamerica.
El Caracol takes its name, Spanish for “snail,” from the spiral staircase inside the building.
UNESCO notes that the architecture combines Maya building techniques with elements from central Mexico. That mix is one of the reasons the site is listed.
Protection and World Heritage status
Chichen Itza was inscribed on the UNESCO World Heritage List in 1988 under cultural criteria i, ii and iii. Its protection rests on Mexico’s 1972 federal monuments law. A presidential decree made the area an archaeological monument in 1986.
FAQ
How do you pronounce Chichen Itza?
The Spanish pronunciation is [tʃiˈtʃen iˈtsa]. The last syllable of each word is stressed.
What does Chichen Itza mean?

Where is Chichen Itza located?
It is a pre-Columbian Maya city on Mexico’s Yucatán Peninsula, between Valladolid and Mérida.
When can you see the serpent on the Kukulkan Pyramid?
Around sunset near the spring and autumn equinoxes. The Exploratorium says the effect can also be seen about a week before and after each equinox.
Was the serpent effect designed for the equinox day?
Nobody can say for certain. The Exploratorium notes that the builders’ intent cannot be known. Archaeoastronomers Ivan Šprajc and Pedro Francisco Sánchez Nava argue the pattern cannot mark the exact day, because it appears before and after it.
