Archaeologists have uncovered the Golden City, which had been lost for hundreds of years.

For centuries, explorers have searched for the Lost City of Gold known as Païtiti, which many believed to be hidden in unexplored regions of the Amazon. The legend of Païtiti inspired Sir Arthur Conan Doyle’s “The Lost World,” and over time, treasure hunters, archaeologists, and explorers have all been drawn to the idea of discovering this magical kingdom. Now, a remote location in the Peruvian Amazon, thought to be the fabled Lost City, has been discovered and is the target of a professional expedition this summer.

According to Inca traditions, the city lies deep in the jungle, east of the Andes area of Cusco, and may have been the last Incan refuge following the Spanish conquest. The Spanish conquistadors pillaged Cusco for its gold and silver, but the bulk of the treasure was never found. Recently, a Spanish galleon that sank over 300 years ago was discovered off the coast of Colombia, possibly holding billions of dollars worth of loot from Peru.

In 2001, the discovery of uncharted Inca terraces at Choquecancha offered a possible path to the elusive city of Paititi. The search for Paititi had been ongoing for centuries, but it wasn’t until Italian archaeologist Mario Polia stumbled upon a report by missionary Andres Lopez in the Vatican archives that the possibility of its existence gained real traction. Lopez’s detailed description of a large city in the middle of the tropical jungle, rich in gold, silver, and jewels, sparked immense curiosity among scholars and explorers alike. However, the Vatican kept the location of Paititi a secret for decades.

To truly grasp the significance of this discovery, one must first understand what Paititi represents. Most commonly believed to be the last refuge of the Incas, Paititi may have actually been home to the Chachapoyas, a tribe of skilled warriors and builders who were ruled by the Incas in the North Cusco region. Through extensive research, scientists have begun to unravel the mysteries of this ancient city, offering glimpses into a culture that has long been shrouded in secrecy.

Before the arrival of the Spanish in South America in 1532, the Inca Empire of Tawantinsuyu, meaning “Four Quarters” in the Quechua language, was the dominant political power on the continent. Governed from its capital in Cusco, the Inca Empire controlled vast territories spanning parts of Peru, Ecuador, Colombia, Bolivia, Chile, and Argentina. Although highly advanced in political, administrative, and urban aspects, the Inca civilization lacked the use of horses, armor, and firearms for warfare. Armed only with bows and arrows, the Inca warriors were no match for the brutal Spanish conquistador, Francisco Pizarro, and his men. With just two hundred followers, Pizarro was able to capture the Inca emperor, Atahualpa, and force his warriors to retreat. The remnants of Inca royalty escaped to Vilcabamba, situated in the jungle-covered lowlands northwest of Cusco.

However, after a few decades, their small state fell, and the last Inca ruler, Tupac Amaru, was captured and executed. Thus, the final chapter of the Inca story came to an end. In the following centuries, the ruins of Vilcabamba and its whereabouts slipped into oblivion as the forest gained the upper hand.

As time passed, rumors began to circulate about a mysterious and significant undiscovered center of Incan civilization called Paititi. According to various legends, this hidden city is located in the wild and uncharted region northeast of Cusco. Despite centuries of attempts by explorers using old maps and accounts, the harsh environment, wildlife, and terrain have prevented any relevant discoveries regarding the true location of Paititi.

However, Paititi Research is now changing the game with a scientific approach to exploration. Rather than blindly venturing into uncharted territory, extensive research has been completed first, and this method is already yielding many positive results. The team’s efforts to gather information and analyze data provide a promising foundation for future explorations, bringing us closer to uncovering the long-lost city of Paititi.

Paititi, a legendary lost city, remains elusive due to its location in uncharted territory, rugged terrain, and dense vegetation. Despite these challenges, Paititi Research has developed innovative methods to narrow down potential hiding places. By utilizing advanced remote sensing technology and geo-information systems (GIS), the team has access to up-to-date information about even the most inaccessible regions. Additionally, GIS tools enable the organization of large datasets and thorough geospatial analysis, aiding in the search for Paititi. These cutting-edge techniques have given hope to the possibility of discovering this long-lost city.

PaιTiti Research utilized specialized software such as PostGIS, Earth Engine, and QGIS to create a comprehensive GIS and database that amalgamated all sorts of data related to the mysterious city of Paititi. This comprehensive collection of information included satellite and aerial images captured by advanced technologies like GeoEye-1, RapidEye, and UAVSAR, along with old and modern maps, written and verbal testimonies, results of other expeditions, authentic documents, and legends. This vast repository of data resulted in unprecedented outcomes and enabled Paititi Research to conduct sophisticated geographic analyses, such as assessing the morphometric characteristics of the terrain, modeling water flows, calculating incoming solar radiation, exploring landscapes in 3D, and more. By analyzing all this data, Paititi Research was able to narrow down the area that potentially could contain the legendary city of Paititi.

The creation of a river network map in a target region was a critical step in the search for PaiTiti, an elusive lost city. Literary sources, old maps, and verbal accounts mentioned rivers as important landmarks in the area. Therefore, in order to study and apply the information from these sources, a map with river names was needed. Paititi Research utilized a digital elevation model (DEM) to build a river network and label the river names in the target region. The process involved georeferencing old maps and aligning them with the distinct meanders of known rivers, as shown in the screenshot above. With this accurate and detailed river network map, Paititi Research was able to continue their search for the fabled city with renewed hope and confidence.

One crucial aspect required in creating accurate maps was the incorporation of morphometric relief characteristics of potential areas. Mountainous environments restrict movement, making it impossible to establish settlements on terrain with steep slopes. Several studies conducted in the Alpine region have already validated this concept. Therefore, the surface steepness of both ancient and contemporary settlements in the region of interest, such as the ruins of Vilcabamba and the Yavero River valley, were meticulously analyzed. The findings indicated that all settled locations had a slope grade of less than twenty degrees, significantly limiting the areas where the legendary PaiTiTi could possibly be found.

Additionally, in order to determine the most favorable areas for life, Paititi Research created a comprehensive solar radiation distribution map. Identifying areas with inadequate solar radiation, the team utilized radiation levels from existing ruins and modern settlements to narrow down potential locations containing PaiTiti. In order to better interpret these maps, Paititi Research employed three-dimensional modeling techniques.

From these maps, thematic maps were created, including the Passability Map and the Settlement Suitability Map. The Passability Map was generated through surface slope and tree density analysis and indicates areas that are either easily passable or impassable on foot. This information was crucial in planning the Paititi Research team’s expedition routes, with dark green areas indicating highly passable regions and red signifying those that are virtually impossible to traverse.

Overall, Paititi Research’s cutting-edge mapping and analysis methods have yielded invaluable insights into the location of PaiTiti, paving the way for future expeditions to uncover this elusive and enigmatic site.

In addition, the team at Paιtitι Research has developed a Settlement Suitability Map that takes into account slope steepness and solar radiation, as explained earlier. This innovative map identifies flat, well-lit areas that are optimal for human activities, and it has the potential to uncover previously undiscovered Incan archaeological sites. A fascinating glimpse of the Settlement Suitability Map in action can be seen in the image below, which shows a fragment of the map in the Machu Picchu region.

The Settlement Suitability Map fragment shows the suitability of the area around Machu Picchu for settlement. The Inca site is situated in a green zone, indicating that the area is suitable for habitation. Conversely, regions highlighted in red are highly unsuitable. Our initial research area covered approximately 1300 square kilometers. However, after mapping settlement suitability, we focused on highly suitable zones and studied high-resolution imagery using different spectral ranges such as visible, near-infrared, and microwave. This approach revealed patterns and structures that we interpreted as potential archaeological sites, some of which are indicated below. The three images depict the same area but highlight different aspects, including a multi-spectral optical image, a settlement suitability map, and a radar image.

The PaiTiti Research team’s work has yielded some exciting results, including a single area highlighting three different aspects: a multi-spectral optical image, a settlement suitability map, and a radar image. However, perhaps the most impressive result is the team’s reconstruction of the ancient Inca road system for the region of their study, using terrain parameters, satellite imagery, and knowledge of existing ruins and Inca trails. The resulting Potential Inca Road Network map is not only an impressive feat of cartography but also a valuable resource for archaeological research. The GIS screenshot below showcases a fragment of the map, with discovered Inca trails depicted in continuous orange lines and reconstructed paths in dashed lines, superimposed on a high-resolution satellite image.

The Paititi Research team has been tirelessly working on their mission to uncover the secrets of the Lost Incan City since the beginning of 2017. Using a combination of cutting-edge technology and traditional research methods, they have meticulously analyzed and evaluated a vast amount of materials in order to identify potential sites. After considering six candidates, the team organized a land expedition in June of 2019 to refine their digital research model and gather new information. The journey was arduous, taking them through the rugged terrain of the Andes, where they faced injury and encounters with wildlife. Despite these challenges, the team persevered and made remarkable discoveries, including previously undiscovered Incan terraces in Choquecancha. Their research efforts have proven that there is still much to be uncovered about the mysterious and enigmatic Paititi. A screenshot of their GIS map, with continuous orange lines representing discovered Inca trails and dashed lines representing reconstructed paths overlaid on a high-resolution satellite image, showcases the progress they have made in uncovering the secrets of this lost city.

The expedition team navigated a challenging route and was composed of four skilled members. Their hard work paid off as Paititi Research was able to select one candidate from the six potential options, upon which they are now focusing all of their efforts. The team is determined to consolidate their research findings and is currently working on a paper for a prestigious peer-reviewed journal. Additionally, they are actively establishing relationships with universities in Peru to garner support for their final expedition, which will ultimately confirm or disprove their discoveries.
