A sprawling Maya metropolis, hidden for centuries beneath dense tropical canopy, is coming into focus as archaeologists combine laser mapping, on‑the‑ground excavation and even chance encounters in the jungle. The newly documented city, part of a wider complex now known as Valeriana, is forcing researchers to rethink how many people once lived in the forests of southern Mexico and Guatemala and how sophisticated their urban planning really was. I see this discovery as less a single eureka moment than the latest, clearest sign that the Maya lowlands were once as densely organized as any premodern heartland on Earth.
The jungle metropolis of Valeriana takes shape
The city now called Valeriana sits in the tropical rainforests of the Mexican state of Campeche, where thick vegetation long hid its plazas, causeways and pyramids from view. Archaeologists had known of a lake named Laguna la Valeriana for years, but only systematic mapping revealed that the surrounding ridges and bajos were packed with architecture, confirming Valeriana as a major Maya urban center. The site lies in the same broad forest belt that has already produced monumental complexes such as the Zona Arqueológica de Ocomtún, where visitors today can walk among towering structures at the officially designated Zona Arqueológica de.
What makes Valeriana stand out is its sheer scale and density. Recent research using laser imaging has identified over 6,700 pre‑Hispanic structures spread across the surrounding landscape, a pattern that suggests not a single isolated city but a network of interconnected neighborhoods and satellite communities. In reports on the new mapping, archaeologists describe Valeriana as part of a vast settlement system in Campeche, with causeways and terraces tying together ceremonial cores, residential compounds and agricultural zones across rugged terrain, a picture that aligns with earlier lidar‑based work on a huge Maya city that emerged from the jungle in Mexico.
How laser surveys pierced the canopy
The breakthrough at Valeriana rests on lidar, a technology that fires pulses of laser light from aircraft and measures their return time to build a high‑resolution model of the ground surface. Archaeologists emphasize that, Because lidar allows them to map large areas very quickly and at very high precision and levels of detail, they can now see platforms, causeways and even small house mounds that would be almost impossible to detect on foot in such dense forest. In the case of Valeriana, a detailed lidar survey over the Campeche region revealed a lattice of rectilinear compounds, plazas and roads that immediately signaled a major city rather than scattered hamlets.
Similar methods have transformed other parts of the Maya world. Aerial lidar surveys have uncovered ancient settlements in the Campeche region that match the pattern of a Vast ancient Mayan city found in a Mexican jungle, where researchers used an Aerial campaign to trace causeways and defensive works across a broad swath of Campeche. Another project, Using a detailed lidar survey that targeted specific ridges and valleys and relied on precise measurement of laser returns, identified a Maya city with pyramids, plazas and a ballcourt in the Mexican jungle, underscoring how quickly entire urban layouts can now be reconstructed from the air without cutting a single trail through the forested terrain.
From chance encounters to student‑led finds
Even as high‑tech mapping reshapes the field, some of the most striking discoveries still begin with human happenstance. A huge Maya city has been described in one report as having come to light almost by accident, when ground teams followed up on anomalies in the jungle and realized they were walking through the remains of a metropolis that flourished from 750 to 850 AD, a period when climate change is thought to have played a major role in its eventual abandonment. Archaeologists working in that region stress that they cannot be sure what led to the demise of the city, but the combination of environmental stress and political upheaval fits patterns seen across other sites.
New voices are also driving the research. A graduate student named in one report as Lauren Keenan, who had worked as an anchor and reporter for Straight Arrow News, helped bring wider attention to an ANCIENT MAYAN CITY buried centuries ago in the jungles of Mexico after a field campaign documented its plazas and causeways. I see that story, highlighted in coverage that referenced the phrase ANCIENT, MAYAN, CITY, as emblematic of how younger researchers are now at the forefront of jungle exploration, blending media savvy with traditional survey skills to explain why these ruins matter to contemporary audiences.
A wider wave of “lost city” revelations
Valeriana is part of a broader pattern in which entire urban landscapes, long dismissed as empty rainforest, are being reclassified as densely settled cultural heartlands. Recent research has revealed the existence of ancient Mayan settlements across a huge area, with the Valeriana mapping alone documenting over 6,700 pre‑Hispanic structures and showing how terraces, reservoirs and roads linked multiple centers into a single engineered environment. Reports on Valeriana describe how this network sits within a larger mosaic of Maya sites in Campeche, reinforcing earlier lidar work that had already hinted at a continuous belt of urbanization in this part of Mayan territory.
Other regions are yielding comparable surprises. Archaeologists have uncovered a previously unknown Maya city beneath dense jungle using Lidar technology, which allowed them to map the settlement without disturbing a single tree and to trace its streets and plazas in three dimensions. In another case, researchers have found almost 1,000 previously hidden Maya settlements in the tropical lowlands of what is now northern Guatemala, a figure that underscores just how incomplete earlier maps of the Maya world really were and how much remains to be documented in Jan and beyond. One video report on this northern zone notes that researchers have identified almost 1,000 such sites in Guatemala, highlighting the scale of the transformation in our understanding of ancient Guatemala.
Rebels, white jaguars and ancestral couples
The new city in Campeche is not the only discovery rewriting Maya political history. In the dense jungles of Chiapas, Mexico, archaeologists have uncovered the long‑lost city of Sac Balam, described as the Land of the White and associated with Maya rebels who resisted the Spanish conquest for more than a century. Reports on Sac Balam emphasize that In the forests of Chiapas, Mexico, this stronghold functioned as a refuge for insurgent communities, adding a new chapter to the story of resistance and survival in the colonial era and linking the site to later legends about a lost land of the white jaguar that some researchers had been seeking for Sac Balam.
Those legends have echoed in popular media, where one account notes that archaeologists finally pinned down the location of the lost land of the white jaguar after 300 years of searching, a narrative that dovetails with the historical Sac Balam discoveries even if some details remain debated. Farther south, in Guatemala, excavations have revealed the remains of a Mayan city nearly 3,000 years old named Los Abuelos, which takes its name from two human‑like sculptures of an ancestral couple found at the site and dated to between 500 and 300 BC. I see Los Abuelos, with its focus on an “ancestral couple,” as a reminder that these cities were not just political capitals but also places where origin stories and family lineages were anchored in stone, a pattern that resonates with community traditions still visible at modern sites such as the Balneario El Abuelo complex and the nearby Los Abuelos ruins.
