There's a Maya city split in two by a border drawn a thousand years after its abandonment. On the Belizean side, archaeologists call it El Pilar; on the Guatemalan side, Pilar Poniente. The temples are the same, the plazas are the same, the jungle that covers them is the same: only the line on the map is new. And there's something even more puzzling: although it was considerably larger than the famous Xunantunich, almost no one visits it, because here it was decided —deliberately— not to clear the jungle from the pyramids.
El Pilar is an extensive Maya archaeological site in western Belize, in the Cayo District, on the border with Guatemala. Its official name is the El Pilar Archaeological Reserve for Maya Flora and Fauna, a name that already announces its dual character: it's not only a site of ruins, but also a protected area of tropical jungle. The complex lies about 12 kilometers north of the village of Bullet Tree Falls, near San Ignacio.
What distinguishes El Pilar from most Maya cities is that its structures extend on both sides of the current international border. The eastern sector lies in Belizean territory and the western one —called Pilar Poniente— in Guatemalan territory. Of course, that political line didn't exist in Maya times: for its inhabitants, El Pilar was a single great city, organized around several plazas and monumental complexes. The modern border simply crosses it.
The dimensions of the site are notable. El Pilar is considered to have been much larger than the nearby and famous Xunantunich, with dozens of important structures and a considerable monumental area. That scale, plus its strategic location in the Belize River valley, suggests it was one of the most relevant Maya centers in the whole region for centuries.
El Pilar had an extraordinarily long history of occupation. The evidence indicates that the city began to be settled in the Middle Preclassic, around 800 BC, and that it remained inhabited and expanding until the end of the Classic period, around AD 1000. That means more than a millennium of continuous life, during which its plazas, temples, palaces and residential areas were built, expanded and remodeled.
During the Classic period (roughly AD 250 to 900), which was the heyday of Maya civilization in the Lowlands, El Pilar reached its maximum extent and population. Its location in the fertile Belize River valley, with good land and access to water, favored an economy based on agriculture, complemented by regional trade. The city functioned as a political, ceremonial and economic center for a large population dispersed in the surroundings.
Like so many Maya cities of the Lowlands, El Pilar was abandoned toward the end of the Classic, in the context of the so-called 'Maya collapse', a complex process in which factors like droughts, environmental pressures, conflicts and political transformations combined. The jungle covered the structures again for centuries, until modern archaeology rediscovered them and began to study them.
Although the existence of ruins in the area was known before, the systematic study and development of El Pilar are closely tied to the work of the archaeologist Anabel Ford, of the University of California, Santa Barbara, who began her research in the Belize River region and concentrated on El Pilar from the 1990s. Ford documented the enormous extent of the site and its cross-border character, and became its main promoter.
The most characteristic feature of Ford's approach was her conservation philosophy. Instead of clearing the jungle to display the bare stone structures —as is done at most Maya sites— she proposed keeping the buildings under the forest canopy, a strategy she called 'archaeology under the canopy'. The idea is that the vegetation protects the stone from the erosion of sun and rain, reduces maintenance costs and, moreover, conserves the jungle ecosystem that surrounds the ruins. That's why many structures of El Pilar look like tree-covered hills, with sections exposed at specific points.
This approach made El Pilar an international case study on how to manage archaeological heritage sustainably, integrating cultural and natural conservation. The reserve combines the protection of the ruins with that of the tropical forest and its wildlife, in a proposal that dialogues with the way the Maya themselves would have coexisted with their environment.
One of the most original contributions of the El Pilar project is the attention to the Maya agricultural system and its link with the jungle. The archaeologist Anabel Ford and her collaborators developed the idea of the Maya 'forest garden': a model of agriculture that does not raze the jungle to impose monocultures, but imitates it, combining useful trees, medicinal plants, fruit trees and crops in different strata, like the layers of a forest.
At El Pilar, next to the reconstructed Maya house called Tzunu'un, a forest garden was recreated to show how the ancient Maya could sustainably manage the resources of the jungle for centuries. According to this interpretation, much of what today looks like 'pristine' jungle in the region would, in reality, be a landscape shaped by generations of Maya who cultivated and selected useful species: an inherited 'forest garden'.
This component directly links archaeology with today's communities. The project worked with contemporary master 'forest gardeners', keepers of that traditional knowledge, to document and keep those practices alive. Thus, El Pilar is not limited to conserving ancient stones: it also seeks to preserve and revalue an ecological wisdom that connects the Maya of the past with their descendants today.
The cross-border character of El Pilar made it something more than an archaeological site: a symbol of cooperation between Belize and Guatemala, two countries whose border has historically been the subject of territorial disputes. Since the ancient Maya city extends on both sides of the border line, its conservation requires, in theory, the coordination of the two states and of institutions on both sides.
From the project, the idea was promoted of managing El Pilar as a peace park or binational protected area, in which the modern border is not an obstacle to protecting a heritage that belongs to the same culture. This vision aims for the ruins and the surrounding jungle to be conserved as a whole, without the political division fragmenting the site or its ecosystem.
In practice, coordination between countries and the management of a remote, jungle site pose challenges, and access and rules may vary over time. But the proposal of El Pilar —shared cultural and natural heritage, conserved through cooperation— remains an internationally cited example of how the Maya legacy can build bridges over today's borders.
