In late October, Oaxaca smells different. Marigolds, burning copal, toasted chiles and fresh bread fill the streets, the markets and every family kitchen.
The reason is the altar de muertos, or ofrenda: a table families build to welcome their loved ones home for Día de Muertos. It is not a decoration. It is an invitation.
This guide explains the history of the Oaxacan altar, what goes on it, what each piece means, and why food sits at its heart. At the end, we'll show you how to taste it for yourself in a cooking class just outside Oaxaca City. For the full festival calendar and where to go, see our complete guide to Day of the Dead in Oaxaca.
What Is an Altar de Muertos?
An altar de muertos is an offering built to honor family members who have died. Tradition holds that their souls return once a year, and the altar is where they are received.
It usually stands inside the home, but you will also see altars in markets, schools, restaurants and town squares. Each one is personal: a portrait of who someone was and what they loved.
The idea behind it is simple. Death does not end the relationship. For a few days, the family sets the table for those who are gone, just as it would for any honored guest.
The History of the Altar de Muertos in Oaxaca
The altar you see in an Oaxacan home today is the result of more than a thousand years of history. Here are the key moments:
Before 1521 · Zapotec and Mixtec ancestors. For the peoples of Oaxaca, the dead remained bound to the family and the land. Mitla, one of their sacred centers, says it in its name: it comes from the Nahuatl Mictlán, "place of the dead," and in Zapotec it is called Lyobaa, "place of rest." Sources also mention Pitao Bezelao, the Zapotec lord of the underworld.
The archaeological proof: Tomb 7 at Monte Albán. In 1932, archaeologist Alfonso Caso discovered a tomb at Monte Albán holding one of the richest funerary offerings in the Americas: Mixtec jewelry of gold, jade and turquoise. In Oaxaca, honoring the dead with the most precious things is a custom more than a millennium old.
The Mexica feasts of the dead. Sixteenth-century chroniclers such as Fray Diego Durán described two feasts in the Mexica calendar dedicated to the dead: Miccailhuitontli, for children, and Huey Miccailhuitl, for adults, held around August and September. These were Mexica (Aztec) feasts; each people of Oaxaca had its own rites.
1529 · The Dominicans arrive in Oaxaca. Dominican friars took charge of evangelizing the region, and the rites for the ancestors were folded into the Catholic calendar: All Saints' Day (November 1) and All Souls' Day (November 2), a commemoration instituted by Saint Odilo, abbot of Cluny, around the year 998. Candles, crosses, saints and wheat bread joined copal, marigolds, corn and cacao. From that blend came the altar we know today.
1910–1913 · Posada's skeleton. Printmaker José Guadalupe Posada etched the "Calavera Garbancera," a satire of Mexicans who denied their Indigenous roots. In 1947, Diego Rivera painted her in his mural Dream of a Sunday Afternoon in the Alameda Central, and that is where the name Catrina comes from.
Today · Oaxaca, a world reference for Día de Muertos. The muerteadas of the Etla valley, the comparsas, the sand tapestries and the candlelit cemetery vigils keep the tradition alive. In 2008, UNESCO inscribed the Indigenous festivity dedicated to the dead on the Representative List of the Intangible Cultural Heritage of Humanity.
Across all these centuries, the core idea has not changed: food, flowers and memory hold the family together.
What Makes a Oaxacan Altar Different
Altars across Mexico share the same spirit, but three details tell you you're in Oaxaca:
The arch (arco). A curved frame of cane stands over the altar, woven with marigolds and velvety red cresta de gallo flowers. It marks the doorway between the world of the living and the world of the dead.
Fruit and sugarcane. Oaxacan altars overflow with oranges, limes, tejocotes, bananas, peanuts and whole stalks of sugarcane — the harvest of the season, offered back.
Bread with a face. Oaxaca's pan de muerto is a rich egg-yolk bread topped with a small painted dough face, called a carita. It stands for the souls being remembered.
There is no single "correct" altar. Traditions shift from the Central Valleys to the Mixteca, the Sierra, the Isthmus and the coast. Every family adds its own story.
When Is Día de Muertos in Oaxaca?
The main days are October 31 to November 2, but preparations start weeks earlier. Markets fill with marigolds, bread and sugar figures from mid-October.
Late October: families shop the markets and build the altar.
October 31: the souls of children (angelitos) arrive.
November 1 (All Saints' Day): children depart and adults arrive.
November 2 (All Souls' Day): adult souls are honored and bid farewell.
Exact customs vary by town and by family. Some communities also set aside a day for those who died suddenly or by accident.
What Each Element of the Altar Means
Every object on the altar has a job. Together they guide the soul home and make it feel welcome.
Marigolds (cempasúchil): their color and scent light the path home. Petals often trail from the door to the altar.
Copal: a tree resin burned as incense. Its smoke cleanses the space and carries prayers.
Candles: light to guide the way. Some families light one for each person remembered.
Water: quenches the thirst of a soul after its long journey.
Salt: purifies and protects.
Photographs: show who is being honored.
Personal objects: a hat, a guitar, a deck of cards — the things that made someone who they were.
Food and drink: their favorite dishes, so they can enjoy the essence of the meal once more.
The most meaningful altar is not the biggest. It is the one that best remembers the person.
Common Myths About the Altar de Muertos
"The seven-level altar is pre-Hispanic." There is no record of seven-level altars in the historical sources; it is a recent interpretation popularized online. In Oaxaca, many families set their offering on a single table beneath the arch. What matters is not the number of levels, but who is remembered.
"La Catrina is an ancient goddess." No. She was created by José Guadalupe Posada in the early twentieth century and popularized by Diego Rivera.
"Day of the Dead is Mexican Halloween." They are different traditions. Halloween has Celtic and Anglo-Saxon roots; Día de Muertos blends Indigenous and Catholic rites to welcome loved ones home, not to scare them away.
"It all comes from the Aztecs." Mexico is home to dozens of Indigenous peoples, each with its own customs. In Oaxaca, the roots are mainly Zapotec, Mixtec and those of the state's other peoples.
Food: The Heart of the Oaxacan Altar
Cooking a loved one's favorite dish is a way of saying: we remember you, and you are still part of this family.
In Oaxaca, that cooking often takes days. Families gather to toast chiles, grind cacao and fold tamales — and while they work, they tell stories about the person they are honoring.
The most common offerings:
Mole negro. Oaxaca's most celebrated dish: dozens of ingredients, from chilhuacle chiles to chocolate, toasted and ground into a deep, dark sauce. Making it is a family ritual. (Go deeper in our mole negro guide.)
Tamales. Wrapped in banana leaf and often filled with mole, they are made by the dozen to share with neighbors and visitors.
Hot chocolate. Oaxacan chocolate is stone-ground cacao with sugar, cinnamon and almonds, whisked with water or milk until it foams.
Pan de muerto. The egg-yolk bread with its painted face, made to be dipped in that chocolate.
Mezcal. Oaxaca's signature spirit, poured for the grown-ups who enjoyed it in life. (Learn more in our mezcal guide.)
Seasonal fruit and sweets. Oranges, tejocotes, candied pumpkin and sugar skulls.
After the souls have taken the "essence" of the food, the living share it. The altar becomes a family meal.
Experiencing Día de Muertos in Oaxaca, Respectfully
From October 31 to November 2, the cemeteries around Oaxaca City glow with thousands of candles. Families clean and decorate graves, share food, play music and stay late into the night. The most famous is the Xoxocotlán cemetery, just south of the city, where families keep an all-night candlelit vigil on October 31. It is moving — and it is a family moment, not a show.
A few simple rules go a long way:
Ask before you photograph people, graves or private altars.
Never touch offerings or decorations.
Keep your voice low and give families space.
Skip the costume. Día de Muertos is not Halloween.
Support local. Choose local guides, markets, artisans and cooking classes, so the benefit stays in the community.
The best way to understand a culture is to ask, listen and taste.
