# Roughly 2,500-year-old observatory discovered in Mexico

### Discovery and Dating

Archaeologists in Mexico have identified a monumental complex at **Teteles de Ávila Castillo**, in the Sierra Norte mountains of Puebla, as a possible ancient solar observatory dating to roughly **2,500 years ago**. The findings, announced by Mexico’s National Institute of Anthropology and History (INAH) on October 13, place the site’s development in the **Middle Preclassic period, approximately 1000 to 600 BC**.

The settlement, historically known as **Tetelihtic**, contains pyramidal structures, ceremonial plazas and large stone platforms. According to the report, researchers believe the arrangement of these features was deliberately designed to track the Sun’s changing position along the horizon. If confirmed, the site would provide further evidence that early Mesoamerican communities integrated astronomical observation into both architecture and religious practice centuries before the rise of Teotihuacan and the later Maya civilization.

### Architectural Alignment

The central feature of the interpretation is a pair of monumental platforms separated by a quadrangular courtyard. The eastern platform measures approximately **90 metres long and 40 metres wide**, while the western structure is about **46 metres by 27 metres**.

Researchers propose that observers stood on the western platform and watched the Sun rise above or near the eastern structure. As the year progressed, sunrise would appear at different points along the horizon. Those changing positions could then be used to identify recurring astronomical events, effectively turning the settlement’s architecture and surrounding mountain landscape into a long-term calendar.

The report states that the alignment appears capable of marking the **solstices and equinoxes**, when the Sun reaches important points in its annual cycle. Such observations would have required repeated monitoring over time and the ability to convert those observations into a carefully planned architectural layout. The construction therefore suggests not only practical knowledge of seasonal patterns, but also the social organization needed to build and maintain a large ceremonial complex.

### Agricultural and Ceremonial Significance

According to the findings described by INAH, the eastern platform may have been oriented not solely toward the equinoxes, but toward dates associated with the beginning of the **Mesoamerican calendar in February** and the **harvest season in October**. These periods would have been especially important to agricultural communities dependent on seasonal rainfall, planting and crop collection.

The scale of the complex indicates that the site’s purpose likely extended beyond a simple tool for farming. Its platforms and plazas formed part of a sacred centre, suggesting that the measurement of time was closely connected with ritual activity and political or religious authority. In this interpretation, celestial events were not merely observed; they helped structure the ceremonial life of the community.

### What the Evidence Shows

The discovery offers a window into the astronomical knowledge of populations living in Mexico long before later Mesoamerican societies became prominent. It also raises questions about how such knowledge was developed, transmitted and reflected in architectural traditions across the region. The report notes that similar astronomical structures appeared hundreds of kilometres away, although it provides no further details about those comparisons.

The available account also mentions possible evidence that the builders observed objects beyond the Sun, but the supplied material ends before describing that evidence. **There is no information in the report establishing a connection between Tetelihtic and UFOs, extraterrestrial activity or paranormal phenomena.** At present, the site is best understood as an archaeological example of early Mesoamerican astronomy, ceremonial architecture and the use of the heavens to organize agricultural and religious life.
