Two Indigenous Communities That Survived the Spanish Conquest Discovered in Mexico
Archaeologists in western Mexico have uncovered remarkable evidence of two Indigenous settlements that remained occupied after the Spanish conquest, providing fresh insight into how native communities adapted during one of the most transformative periods in the country's history.
The discoveries were made in the Costa Grande region of Guerrero during archaeological investigations conducted ahead of the planned expansion of the Pátzcuaro–Lázaro Cárdenas highway.

Researchers identified two settlements—Camutla and Sacualpan—that were originally established during the Late Postclassic period and continued to be inhabited after Spanish forces arrived in the early 16th century. Both communities survived until the late 1500s before eventually being abandoned.
Archaeology Supporting Modern Development
The archaeological surveys were conducted between 25 and 30 March 2026 using detailed ground inspections and drone mapping to determine whether the proposed highway could affect previously unknown archaeological sites.
Mexico's Secretary of Culture, Claudia Curiel de Icaza, said the discoveries highlight the importance of integrating archaeology into major infrastructure projects from the earliest planning stages.
According to officials, preserving cultural heritage while supporting modern development allows valuable historical information to be documented before it is lost forever.
Camutla Identified Through Historical Records
One of the newly documented settlements lies on a hill overlooking the La Unión River near the Pacific coast, close to the modern community of El Chico, also known as Capire.
Archaeologists recorded 39 stone structures spread across approximately eight hectares. The settlement includes residential terraces, retaining walls, ceremonial spaces, and several small stone stelae, some of which remain standing today.
Historical documents proved especially valuable in identifying the site. Oral traditions and sixteenth-century records, including the famous Geographical Relations and the Ortelius Map, indicate that the settlement was known as Camutla.
Researchers believe the community remained occupied from around AD 1200 until the closing decades of the 16th century.
Sacualpan Offers New Clues to Colonial-Era Indigenous Life
The second archaeological site had previously been recorded under the name Los Ticuiches but has now been identified as the historic Tolimeca settlement of Sacualpan.
Its most striking feature is a massive ceremonial platform measuring approximately 160 metres by 110 metres. Nearby, archaeologists documented another elongated platform that forms an L-shaped ceremonial complex, surrounded by numerous residential mounds and large concentrations of red pottery fragments.
The discoveries suggest Sacualpan served as an important regional centre before and after European contact.
Evidence of Indigenous Survival After the Conquest
Perhaps the most significant aspect of the discoveries is that both settlements remained inhabited after the Spanish conquest.
Many Indigenous communities across Mexico were relocated during the colonial period as Spanish authorities reorganised settlements, introduced taxation systems, and expanded missionary activity throughout New Spain.
The continued occupation of Camutla and Sacualpan provides valuable evidence that some native populations successfully adapted to changing political and social conditions before their eventual abandonment.
Researchers believe these settlements will help historians better understand how Indigenous societies responded to Spanish colonial rule.
A Region Shaped by Multiple Civilizations
Before the arrival of Europeans, the Costa Grande region occupied a strategic frontier between several Indigenous groups.
The area was inhabited primarily by the Tolimecas and Chumbias while neighbouring territories belonged to the Pantecos and Cuitlatecas. It also experienced political influence from both the Aztec Triple Alliance and the Purépecha Empire.
These overlapping cultural influences created distinctive settlement patterns that differ from many other archaeological landscapes along Mexico's Pacific coast.
Protecting Mexico's Archaeological Heritage
During the survey, archaeologists also examined several nearby archaeological sites, including La Parotita, El Huérfano, La Palanca, Los Metates, La Salada, Las Peñas, Las Arañas, Zorcua and Los Azufres.
Four of these locations lie close enough to the proposed highway route that special conservation measures have been recommended to protect them from future construction activities.
Lead archaeologist Rodolfo Lobato Rodríguez said documenting archaeological remains during infrastructure projects is essential not only for protecting cultural heritage but also for recovering information about Indigenous communities that have long disappeared from the historical record.
Further research is expected to improve understanding of settlement patterns, cultural continuity and Indigenous resilience during the transition from pre-Hispanic Mexico to the colonial period.
Conclusion
The discovery of Camutla and Sacualpan provides rare archaeological evidence that some Indigenous communities continued to thrive after the Spanish conquest, preserving their traditions during a period of profound political and cultural change. As research continues, the two settlements promise to deepen our understanding of colonial-era Indigenous life in western Mexico while demonstrating the importance of integrating archaeology into modern infrastructure projects.
