Researchers have uncovered an ancient Roman stairway, offering a glimpse into the 'lost Pompeii'. This remarkable discovery, made possible by a combination of remote sensing technology, close-range photography, and traditional archaeological techniques, is shedding light on aspects of Pompeii that have been lost over time. The stairway, found within the Casa del Tiaso, a lavish residence in Pompeii, suggests the existence of a tower, a symbol of wealth and power. This finding challenges previous assumptions about the city's skyline and the daily lives of its residents, as it was once thought that such towers were not common in Roman cities. The tower, along with other recently discovered structures, indicates that the inhabitants returned to the ruins a few decades after the eruption, building ovens, mills, and fireplaces in the former ground floors. The digital reconstruction of the Casa del Tiaso, led by Dr. Susanne Muth, aims to include every room, providing a more nuanced understanding of the ancient city and its life. This project, known as Pompeii Reset, utilizes advanced technologies to create 3D models and virtual walk-throughs, offering a unique perspective on the city's past. The team's efforts are part of a broader goal to preserve Pompeii's cultural heritage and understand its historical development, with more than 13,000 rooms excavated since 1748, and one-third of the ancient city still buried under volcanic ash.
