The Lost Maya City of El Mirador: A Forgotten Ancient Capital

Maya causeways (sacbeob) were constructed pathways that connected important centers for living and ritual. These causeways linked cities and city-states, facilitating movement of people, goods, and cultural practices. The Coba-Yashuna causeway, 100 kilometers long, connected communities and demonstrated the sophisticated infrastructure that Maya civilizations developed. These causeways represent a form of built infrastructure that connected Maya urban centers.

The sacsbe (white road) network connected Maya cities across the Yucatan Peninsula, with the route at Sayil extending approximately 20 kilometers to Uxmal, the largest Puuc city. These raised stone roads served as transportation corridors, ceremonial pathways, and symbols of political unity. The arch at Sayil marked the southern terminus of this major road network, demonstrating how Maya cities maintained connectivity despite geographic distances. This infrastructure facilitated movement of people, goods, and ideas between urban centers, supporting trade, religious pilgrimages, and administrative coordination across the Puuc region.

The Maya White Roads (Sacbeob, from 'sac' meaning white and 'be' meaning road) were sophisticated raised highways built by the Maya civilization in dense jungles, marshes, and rocky terrain throughout Mesoamerica. These elevated, plastered paths stretched for miles, physically and symbolically connecting the region's most advanced ancient civilization. The Sacbeob served both practical and symbolic purposes: practically, they connected cities, temples, and communities in a region with no navigable rivers and seasonal flooding that could turn the land into marsh; symbolically, they represented the pathways of power and cosmology, connecting the human world to the realm of the gods. The most famous example is the Sacbeob at Coba in the Yucatán Peninsula, built between 600-800 AD, stretching over 100 km as the longest known ancient road in the Americas. This raised causeway, several meters wide and sometimes several meters above the surrounding terrain, was constructed by mobilizing thousands of workers. The engineering involved clearing and leveling the ground, building high embankments in marshy areas with stone retaining walls, and covering the surface with a layer of crushed limestone plaster that gave the roads their distinctive white color and smooth surface. Unlike Roman roads designed for wheeled vehicles, the Sacbeob were designed for pedestrian travel, with porters carrying loads on their backs and the smooth surface facilitating movement. Archaeological discoveries of temples and altars along the routes confirm their economic importance, while modern Lidar technology has revealed these long, straight lines beneath the jungle canopy. Some villages in the Yucatán still use portions of the Sacbeob as pathways, and in some areas, modern roads follow the ancient routes. The Sacbeob challenge assumptions about ancient engineering, demonstrating that the Maya could build large-scale, durable road networks without wheels, horses, or oxen, perfectly adapted to their environment and serving purposes beyond commerce—also facilitating rituals, politics, and cosmic significance.

The Sacbé, plural Sacbéob, were the white roads that connected cities, temples, and ceremonial centers throughout the Yucatán Peninsula. These elevated paths, constructed with compacted limestone stone and covered with white stucco that shone under the moon, functioned as ceremonial and commercial highways that allowed transit between cities separated by kilometers of jungle. The most famous connects Coba with Uxmal along 18 kilometers, but there are records of Sacbéob connecting Coba with Yaxuna along more than 100 kilometers. What recent research has begun to reveal is that, in addition to surface Sacbéob, the Maya constructed underground passages connecting buildings within cities and possibly extending beyond urban limits. These tunnels have been found in several archaeological zones, but in Yucatán most remain sealed because the limestone rock is porous and unstable, and opening a Maya tunnel can cause collapse of structures above. Archaeologists who have documented some passages describe low-ceiling corridors lined with stucco connecting temples with palaces or with subterranean chambers of ritual use. In some cities, tunnels leading to hidden cenotes beneath buildings have been found. These are closed to the public and in many cases not even marked to prevent anyone from attempting entry on their own. The subsurface of Yucatán is perforated with paths that have not been traversed for more than 1,000 years.

Sacbe (or sacbé) were white roads or causeways that connected different architectural complexes and sometimes different Maya cities. These roads were constructed as rectangular channels with retaining walls on both sides, filled with rocks and sascab (white earth), and covered with stucco, which gave them their characteristic white appearance. The sacbe at Choclán served as a pathway connecting this peripheral site to the ancient urban center of Uxmal (now Mérida).

The Mesoamerican ball game was ritual rather than sport, symbolizing the sun's eternal motion. Teams used hips, knees, elbows, and shoulders to keep a 6-8 inch rubber ball aloft without touching the ground. Only capital cities possessed ball courts, symbolizing political power. For water management in the tropical forest with no major rivers or groundwater, the Mayans engineered innovative solutions: raised fields with irrigation/drainage canals, and massive reservoirs constructed from quarried limestone covered with waterproof clay. These reservoirs collected rainwater from building surfaces and filtered it through quartz sand layers. This hydraulic engineering supported populations of 40,000-60,000 during the dry season when rainfall could cease for 3-6 months.

The Valley of Mexico developed sophisticated water management systems dating back to pre-Hispanic times, centered on the pila real (royal weir) at San Juan Atlamica. This ancient structure controlled water distribution from the Río Cuautitlán through five canals (asequias) to surrounding municipalities including Tultepec, Chimalhuacán, Teoloyucán, and Tultitlán. The system served dual purposes: distributing water for agriculture and controlling floods that historically devastated the region. Colonial engineers expanded this infrastructure, creating the Tajo de Nochistongo project that employed nearly 60,000 workers to divert water away from Mexico City. This ancient engineering knowledge, combined with colonial innovations, formed the foundation of modern water management in the Valley.

The Avenue of the Dead at Teotihuacan in Mexico appears to have been designed as a large water basin. The presenter explains that the avenue's design includes features consistent with water collection and management, including rounded stone joints and traces of bitumen. The Great Pyramid of Chichen Itza in Mexico was built over a large underground cistern filled with water, discovered using electrical tomography. The cistern served multiple functions including water supply for the Maya civilization, religious offerings, and diving exploration. The presenter argues that these discoveries support his theory that water management was a deliberate and sophisticated aspect of ancient Mesoamerican construction.

The Aztecs developed an extraordinary hydraulic engineering system to manage water in their island city. They built chinampas (artificial islands) for agriculture, allowing three harvests per year to sustain 150,000 inhabitants. The Nezahualcoyotl dam separated saltwater from freshwater sources, protecting crops. Causeways with gates controlled water flow, opening during floods and closing during dry seasons. The Acueducto of Auitzotl (1499) brought water from Coyoacán but caused flooding when it failed. This system represents one of the most sophisticated water management achievements in pre-Columbian America.

The Mesa Cacahuatenco archaeological zone in Veracruz, Mexico represents one of the largest and most sophisticated ancient civilizations in Mesoamerica, known as the 'City of Water and Gods,' where indigenous peoples like the Nahuatl, Totonaco, and Otomí developed advanced water sustainability systems and held deep reverence for water, with one of their major deities being La Sirena Paco; this site demonstrates comparable architectural and cultural significance to famous Mesoamerican centers like Teotihuacán and El Tajín.

Archaeology has historically served national identity construction, with 19th-century programs used to monumentalize the past and justify nation-states. The apparent objectivity of archaeology masks political and ideological choices in selecting, classifying, and interpreting materials. Contemporary archaeology is intertwined with capitalist practices including heritage marketing, territorial valorization, and development projects serving extractive industries. Yanis Hamilakis has called for radical repoliticization of archaeological ethics, arguing that making the past speak always involves taking positions in present conflicts. Examples include 'archaeology of the perpetrators' in Germany, 'archaeology of the defeated' focusing on forgotten Spanish Republicans, and 'archaeology of the living' with Kurdish communities. This perspective challenges archaeology as a neutral science and recognizes its role in contemporary political struggles.

Contemporary archaeology examines the recent past and how the public interacts with heritage, often overtly political. Since Buckley and Lucas's 2001 work, the field has grown significantly, overlapping with sociology, anthropology, museum studies, geography, and philosophy. It often focuses on ephemeral aspects like protests, conflicts, and waste, built around participatory frameworks. Research centers on making the past relevant for the future, though it risks treating the past as extractive resource.

Heritage protection requires education and public engagement to be effective, enabling community participation in heritage protection decisions and facilitating community reinterpretation of heritage. Cultural parks represent a community-driven approach where local communities participate in heritage protection decisions, reflecting the principle of community ownership of heritage. Contemporary archaeology has expanded to include the study of recent history, including the 20th century and contemporary times, leading to new subfields including archaeology of contemporary cities, villages, forgotten cemeteries, and post-industrial landscapes. Community archaeology involves engaging local communities in archaeological research and decision-making, enabling communities to participate in heritage protection decisions and increasing public awareness of heritage values. Contemporary conservation doctrine requires viewing heritage as an investment rather than an expense, representing a fundamental shift in how heritage is valued and managed.

Archaeology remains relevant to contemporary political issues, including debates about museum collections, repatriation of artifacts, and representation of marginalized histories. The field must maintain rigorous scholarly standards to prevent ideological manipulation of archaeological narratives, ensuring objective documentation of human history.

Contemporary archaeology applies archaeological methods to study recent past contexts, including the 20th century and even the immediate present. This approach treats contemporary sites as archaeological contexts, applying traditional archaeological techniques to recent heritage. The challenge lies in defining what constitutes an 'archaeological context' when dealing with very recent sites, as traditional archaeological methods were developed for ancient contexts.
