Kaminaljuyu: The Highland Maya City Beneath Guatemala City

Kaminaljuyu was one of the largest and most important cities of the ancient Maya highlands, lying in the Valley of Guatemala beneath what is now Guatemala City. At its height in the Late Preclassic period, roughly 400 BC to AD 100, it had hundreds of earthen mounds, irrigation canals and carved monuments with early hieroglyphic texts. Later, in the Early Classic period, it became famous for its close ties to the distant metropolis of Teotihuacan.

Background: the highland Maya

Most people picture the Maya in the lowland rainforests of Guatemala, Mexico and Belize, at cities like El Mirador and Tikal. But the cooler, volcanic highlands to the south were also home to Maya-speaking peoples. Their fertile valleys, sources of obsidian and jade, and position on routes between the Pacific coast and the lowlands made them important for trade.

The Valley of Guatemala was settled by farming villages from around 1500–1000 BC. Kaminaljuyu grew from one of these communities. It was well placed near the El Chayal obsidian source, whose volcanic glass was the main material for cutting tools throughout the Maya world.

A Preclassic city

In the Late Preclassic the city expanded dramatically. Archaeologists have recorded about 200 mounds, the remains of platforms that once supported temples and elite houses, built of earth and clay rather than stone. Its leaders were buried in rich tombs inside the platforms; one, in Mound E-III-3, contained jade, pottery and the remains of people sacrificed to accompany the dead.

Kaminaljuyu’s farms depended on water management. From the Middle Preclassic its people dug the Miraflores canal, drawing water from Lake Miraflores, a lake that once lay in the city. It ran for more than a kilometre and was later joined by other channels. These are some of the earliest large irrigation works known in the Maya region.

Sculpture and early writing

Kaminaljuyu is known for carved monuments in a style shared across the Pacific slope and highlands, related to the art of Izapa. Stela 10, a large fragment of dark basalt, shows figures and a long column of hieroglyphs. Its script is one of the earliest examples of writing in the southern Maya area, though it cannot yet be fully read.

Other monuments show rulers in elaborate costume with deities above them, themes that later became central to Classic Maya royal art. Many carvings were deliberately broken in antiquity, perhaps during conflicts or changes of dynasty.

Trade and power

Much of Kaminaljuyu’s wealth came from its position as a hub of exchange. Obsidian from El Chayal was traded widely, and the city also handled jade from the Motagua valley, cacao and cotton from the Pacific coast, and marine shell. Control over these goods probably helped its rulers build alliances and support large building projects.

The city’s influence reached across the southern highlands and down to the Pacific coast, where related centres such as Takalik Abaj shared its style of sculpture. Some archaeologists think Kaminaljuyu was the capital of a regional state, though the evidence is not conclusive.

Decline and the Teotihuacan connection

Around AD 100–200 Lake Miraflores dried up, the canals went out of use and the city’s Preclassic power faded. Population declined and building slowed.

Kaminaljuyu revived in the Early Classic period. Excavations by Alfred Kidder, Jesse Jennings and Edwin Shook in the 1930s and 1940s found that, roughly between AD 400 and 550, some platforms were built in the talud-tablero style of Teotihuacan, and elite tombs contained Teotihuacan-style tripod vessels and green obsidian from central Mexico. Whether this was a Teotihuacan colony, a local elite adopting foreign prestige or a trading alliance is still debated. The city declined again in the Late Classic and was largely abandoned centuries before the Spanish arrived.

Destruction and preservation

Kaminaljuyu has suffered heavily from modern urban growth. As Guatemala City expanded during the 20th century, most of its mounds were levelled for housing, roads and shopping centres. Only a few remain, protected in the Kaminaljuyu Archaeological Park and nearby areas, and many finds are in the national museum of archaeology in Guatemala City.

Timeline

• c. 1500–1000 BC: Farming villages are established in the Valley of Guatemala.
• c. 800–400 BC: The Miraflores canal is built and the settlement grows.
• c. 400 BC – AD 100: Late Preclassic peak, with large mounds, rich tombs and carved stelae.
• c. AD 100–200: Lake Miraflores dries up and the city declines.
• c. AD 400–550: Teotihuacan-style buildings and tombs appear.
• 1930s–1940s: Excavations by Kidder, Jennings and Shook.
• 20th century: Most of the mounds are destroyed by urban expansion.

Why it matters

Kaminaljuyu shows that Maya civilisation was not limited to the lowland forests. Its canals, sculpture and early writing reveal a major centre of innovation in the Preclassic highlands, and its later Teotihuacan links remain a key clue to how central Mexico and the Maya interacted.
