Ancient Basilica Discovered Beneath Former Fish Market in Italy

Ancient Basilica Discovered Beneath Former Fish Market in Italy

Archaeologists have uncovered the remains of an early Christian basilica beneath the site of a former fish market in northeastern Italy, revealing what is believed to be the oldest known Christian place of worship in the ancient Roman city of Opitergium, now modern-day Oderzo.

The discovery was made during archaeological excavations ahead of a residential development project in Italy's Veneto region. Beneath the former market, researchers uncovered an impressive three-naved basilica dating to the late fourth or early fifth century AD, along with extensive stone foundations and beautifully preserved polychrome mosaic floors.

Experts say the architectural layout and decorative features clearly identify the structure as an early Christian church, providing valuable new evidence of the spread of Christianity during the final centuries of the Roman Empire.

Excavations began in November 2025 after archaeological authorities ordered a full investigation of the site. Located just outside the ancient city walls, the area had already produced significant discoveries in previous years, including Byzantine fortifications, Roman mosaics, and ancient burials, suggesting that important remains still lay hidden underground.

Archaeologists initially uncovered small fragments of decorative flooring before exposing approximately 30 square metres of remarkably preserved mosaics. As excavations continued, they revealed the basilica's perimeter walls, sturdy brick-and-mortar foundations, and large external buttresses. Wooden piles driven deep into the alluvial soil helped support the massive structure, demonstrating sophisticated engineering techniques used during Late Antiquity.

The church featured a rectangular plan divided into three east-west naves. Most of the mosaic flooring survives within the central and southern sections of the building, while smaller portions remain preserved in the northern nave.

The mosaics are among the site's most remarkable discoveries. Rich geometric patterns, floral motifs, interlocking octagons, circles decorated with acanthus leaves, ivy designs, and diamond-shaped panels containing Christian crosses cover much of the floor. One particularly striking section features a large central octagon incorporating a Solomon's Knot surrounded by elaborate decorative borders resembling a ceremonial canopy, highlighting the artistic skill of the craftsmen who created the church.

Excavations also uncovered four graves immediately outside the basilica's southern wall. Three of the burials contained pairs of individuals interred together, an uncommon funerary practice that researchers hope to better understand through future analysis. None of the graves contained burial goods, suggesting changing Christian burial traditions during the period.

Scientists are now carrying out radiocarbon dating on both the human remains and the wooden foundation piles to establish a more precise construction date for the church.

The discovery adds another important chapter to the long history of ancient Opitergium. Originally founded by the Veneti during the 10th century BC, the settlement flourished after the construction of the Via Postumia, becoming one of northern Italy's most prosperous Roman cities with an estimated population of around 50,000 during the second century AD.

Although the city suffered repeated invasions by the Visigoths, Huns, and Ostrogoths during the collapse of the Western Roman Empire, it later emerged as an important Byzantine administrative and religious center before ultimately being destroyed by the Lombards in AD 667.

Local authorities have announced plans to preserve the archaeological remains within the new development. Architects are preparing designs that will allow residents and visitors to view the basilica's mosaics and structural remains while integrating the historic site into the surrounding neighborhood. Officials hope the project will protect this exceptional piece of Italy's early Christian heritage while creating a new destination for cultural tourism.

The discovery offers an extraordinary glimpse into the religious transformation of Roman Italy and provides archaeologists with one of the earliest surviving Christian churches yet identified in the ancient city of Opitergium.

Researchers Rediscover Lost Ming Dynasty Goldsmithing Technique

Researchers Rediscover Lost Ming Dynasty Goldsmithing Technique

Researchers in China have successfully recreated a sophisticated goldsmithing technique that disappeared centuries ago, revealing how Ming Dynasty artisans produced some of imperial China's most exquisite gold jewellery.

The breakthrough, published in npj Heritage Science, focuses on Jin zhe si, an intricate decorative method that transformed ultra-thin sheets of gold into beautifully folded and corrugated designs with a soft satin-like appearance. Although historical documents described the technique, the exact manufacturing process had remained unknown until now.

The research centered on a remarkable pair of gold gourd-shaped earrings recovered from the tomb of Prince Zhu Zairong, a Ming Dynasty prince who died in AD 1545. His burial in Hubei Province has produced some of the finest surviving examples of Ming imperial jewellery, making it an ideal case study for investigating ancient Chinese metalworking techniques.

To uncover the secrets behind the earrings, researchers combined microscopic examination with experimental archaeology. Every detail of the original artifacts was carefully analyzed before scientists attempted to recreate the manufacturing process using traditional methods and historical descriptions preserved in ancient texts.

Their experiments revealed that the key to the technique lay in the extraordinary flexibility of high-purity gold. Researchers compared gold, silver, and aluminum foils under identical conditions and discovered that only nearly pure gold could withstand repeated folding into complex three-dimensional shapes without cracking or breaking.

The study also overturned previous assumptions about how the decorative surface was created. Rather than engraving or embossing the finished jewelry, Ming craftsmen achieved the distinctive satin-like texture by carefully folding and corrugating extremely thin sheets of gold during the manufacturing process itself.

This successful reconstruction bridges a centuries-old gap between written historical records and surviving archaeological evidence. It provides the clearest explanation yet of how Ming Dynasty goldsmiths produced such delicate and intricate ornaments using techniques that gradually disappeared over time.

Beyond solving a long-standing archaeological mystery, the research highlights the extraordinary technical skill possessed by craftsmen working for the Ming imperial court. Their understanding of precious metals allowed them to manipulate gold in ways that continue to impress modern scientists and conservators.

Researchers also believe the project demonstrates the growing value of experimental archaeology in cultural heritage studies. By combining advanced scientific analysis with practical reconstruction, scholars can recover forgotten manufacturing techniques that survive only in archaeological finds and historical documents.

The study further contributes to the preservation of China's traditional craftsmanship by documenting a manufacturing process that had effectively vanished for centuries. The reconstructed method may also assist museum conservators in identifying authentic Ming Dynasty artifacts and improving restoration techniques for historic gold objects.

The research was conducted by Tian Zhihao, Ren Kai, and Jiang Zhenyu of the Gemmological Institute at the China University of Geosciences in Wuhan. Their work offers a remarkable glimpse into the technological achievements of Ming Dynasty artisans and provides new appreciation for one of the finest traditions in the history of Chinese jewelry making.
