The people on the hill
Monte Albán sits on an artificially flattened mountaintop 400 meters above the valley floor, and it was built by hand. The Zapotec civilization began leveling that hilltop around 500 BCE and spent the next thousand years constructing the platform, temples, ball courts, and tombs that you can walk through today. At its height, around 200 CE, Monte Albán held somewhere between 17,000 and 25,000 people — making it one of the earliest cities in the Americas and the dominant regional power in Mesoamerica for more than a millennium.
Nobody fully agrees on why it was built on a hilltop with no natural water source. The standard explanation is defensive — you can see threats coming from any direction across the valley — but some scholars argue the elevated position was primarily religious, placing the city closer to the sky. Both things can be true. What's certain is that the Zapotec chose the most difficult possible location and transformed it into one of the most sophisticated urban centers in the pre-Columbian world.
By around 700 CE, Monte Albán had begun to decline. The reasons are still debated — environmental stress, overextension, conflict — but by 900 CE the city had been largely abandoned. The Mixtec people moved into the region and began using the site for burials, including the remarkable Tomb 7, where excavations in 1932 uncovered one of the richest treasure hoards ever found in the Americas: jade, crystal, turquoise, gold, and bone carved with extraordinary precision. Most of that collection is now in the Regional Museum of Oaxaca.
The valley and its languages
The Valley of Oaxaca sits at around 1,550 meters above sea level, which is why the climate is so agreeable — warm days, cool nights, a rainy season that runs from May through September and keeps the landscape green through the summer. The valley is actually three connected valleys meeting at the city, and the pre-Columbian settlements stretched across all of them. Today you can see their remnants at sites including Yagul, Mitla, Lambityeco, and Dainzú, most of them within an hour of the city center.
The state of Oaxaca contains sixteen recognized indigenous groups and remains one of the most linguistically diverse places in the Americas. Zapotec and Mixtec are the most widely spoken, but you'll also hear Mazatec, Chinantec, Mixe, and several others in the market and on the street. The Zapotec language itself fractures into dozens of variants across different villages — a speaker from the Sierra Juárez can't necessarily understand a speaker from the Isthmus of Tehuantepec. The Mexican government recognizes 57 indigenous languages nationally; more than sixteen of them are spoken in Oaxaca alone.
This linguistic and cultural diversity is visible in the textiles you'll see across the markets. The weaving traditions are village-specific — Teotitlán del Valle produces distinctive wool rugs using natural dyes derived from cochineal insects, indigo, and local plants. San Bartolo Coyotepec produces black clay pottery, an earthenware technique that was revived and popularized in the mid-twentieth century by Doña Rosa Real. Arrazola is one of the centers for alebrijes — the brightly painted carved wooden animals that have become iconic of Oaxacan craft. These traditions are not uniform across the region and were not invented for tourists. They predate the current political boundaries of Mexico by centuries.
The Spanish and what they built
Hernán Cortés arrived in the Oaxacan valley in 1521, the same year he completed the conquest of Tenochtitlán. He was drawn by the region's strategic position and its production of cochineal — the red dye harvested from insects living on nopal cactus, which would become one of the most valuable export commodities in the world for the next two centuries, second only to silver in the colonial economy. Spain guarded the secret of cochineal's insect origin for as long as it could; by the eighteenth century, scientists in Europe were still debating whether the source was a plant seed or a berry.
The city of Antequera — what is now Oaxaca — was formally established as a Spanish colonial city in 1532. The Dominican order arrived in the 1530s and began constructing what would become one of the most significant collections of colonial architecture in Mexico. The Templo de Santo Domingo de Guzmán, begun in 1572 and largely completed by 1608, is the centerpiece. The interior is extraordinary: a gilded ceiling entirely covered in high-relief sculpture and applied gold leaf, a genealogical tree of the Dominican order spreading across the wall above the entrance, side chapels that accumulated silver and color over two centuries of patronage. The church survived conversion into a military barracks during the Reform period and the early twentieth century — a period during which horses were stabled inside — and has been carefully restored.
The attached monastery, one of the largest in the Americas when it was built, now houses the Museum of the Cultures of Oaxaca. The archaeological collection includes the contents of Monte Albán Tomb 7 and artifacts spanning the full pre-Columbian sequence in the valley. It's the best museum in the city and not widely crowded. Budget at least two hours.
Benito Juárez
Mexico's most significant president was born in 1806 in San Pablo Guelatao, a small Zapotec village in the Sierra Juárez, about 65 kilometers north of the city. Benito Juárez spoke no Spanish until he was twelve, when he walked to Oaxaca and went to work in the household of a bookbinder who sponsored his education. He trained as a lawyer, was elected governor of Oaxaca in 1847, and eventually served as president of Mexico for five terms between 1858 and 1872.
The Reform War and the French Intervention are the central episodes of his presidency. After conservatives invited France to intervene and install Maximilian I as Emperor of Mexico, Juárez led the republican government in resistance for five years from mobile headquarters — he was effectively governing Mexico from carriages and makeshift offices in northern cities while a Habsburg archduke held the capital. Maximilian was captured and executed in 1867. Juárez's republican government was restored. The date of the French defeat — May 5, 1862, when outnumbered Mexican forces repelled the French army at the Battle of Puebla — became the holiday you know as Cinco de Mayo.
Juárez died in office in 1872. His house in Oaxaca — the Casa de Juárez, on García Vigil — is a museum. His image appears on the 20-peso note. The central plaza of Oaxaca, which you will spend a significant portion of your time in, is officially the Zócalo but more commonly called the Plaza Benito Juárez. The airport is named for him. He was the first indigenous president of Mexico — and the only one — and his Zapotec background is inseparable from the political project of the Reform: a secular constitutional republic that broke the Church's dominance over land, politics, and civil registration.
The food
Oaxacan cuisine has a specific reputation, and the reputation is justified. The seven moles are the most-cited example — seven distinct sauce preparations, each built from different combinations of chiles, seeds, fruits, and spices, each with a different color and use. Negro, the darkest and most complex, is built around mulato, ancho, and chihuacle negro chiles with chocolate, almonds, raisins, and plantain; it's what appears on enchiladas at festivals and what you'll see ladled over turkey at Christmas. Coloradito is smaller and brighter; verde is herb-forward; amarillo is mild and everyday. The moles are not interchangeable and are not quick to prepare — traditional recipes can require a full day of cooking and several dozen ingredients.
The tlayuda is the form that visitors encounter most often: a large dried tortilla, blistered over coals, spread with black bean paste and asiento (an unrefined pork fat), then loaded with quesillo, the string cheese that Oaxaca is specifically known for, and your choice of meat. The quality varies widely, and the best versions are made by women cooking over wood fires in the market, not in tourist-facing restaurants. Mercado 20 de Noviembre is the canonical address, specifically the corridor of charcoal grills known as the Pasillo de Humo.
Mezcal comes from Oaxaca. More precisely: while tequila is a mezcal made specifically from blue agave in Jalisco and a handful of other states, mezcal as a category is a spirit distilled from the cooked hearts of various agave species, and Oaxaca produces the majority of it. The Valles Centrales around the city have the densest concentration of palenques — small traditional distilleries — in the world. The smoky quality that distinguishes mezcal from tequila comes from roasting the agave piñas in earthen pits lined with hot rocks before fermentation. Different agave species produce distinctly different spirits. Tobalá, which grows wild in the mountains and takes fifteen to thirty years to mature, produces a fruit-forward mezcal that comes in small quantities and at high cost.
Día de Muertos
The Día de Muertos celebrations in Oaxaca run from October 31 through November 2 and are among the largest in Mexico. The observance is not a Mexican Halloween — the origin is pre-Columbian, rooted in Aztec festivals honoring the dead that were later syncretized with the Catholic feasts of All Saints' and All Souls' Day by Spanish missionaries. The result is a holiday that treats death as a return rather than a departure: families build ofrendas — altars with photographs of the deceased, marigold flowers, food, water, candles, and favorite objects — to welcome the spirits of the dead back into the household.
In Oaxaca, the observances extend into the cemeteries. Families spend the night of November 1 at the graves of their relatives, decorating with marigolds and candles, bringing food, playing music, and keeping company with the dead. The cemetery of San Miguel Xoxocotlán, outside the city, is the most visited by outsiders during this period. Processions, sand tapestries, and radish-carving competitions (Noche de Rábanos, on December 23) extend the calendar of public celebrations beyond the core dates.
The UNESCO designation of the holiday as an Intangible Cultural Heritage of Humanity came in 2008. Tourism during the Día de Muertos period has increased dramatically since then. The cemetery observances remain primarily family events; treat them as such.
The thing to carry with you
Most old cities preserve their past in museums and behind glass. Oaxaca's trick is that it never stopped using its past, so there was nothing to preserve. The mole recipes are pre-Columbian techniques applied to ingredients that arrived with the Spanish. The mezcal is distilled in earthen pits that have not changed in design for centuries. The Zapotec languages fragment by village because the villages never merged. The woman selling chapulines in the Mercado 20 de Noviembre is not performing a tradition for you — she is doing what the women at that stall have done since before the building existed. You are not visiting a place that kept its heritage alive. You are visiting a place where the past never became heritage, because nobody stopped doing it long enough for it to need a name.
