Conservation experts and archaeologists are uncovering new details about the tomb of Emperor Otto I while carrying out an extensive restoration project at Magdeburg Cathedral.

Since January 2025, the Saxony-Anhalt Cultural Foundation and the State Office for Heritage Management and Archaeology have led efforts to preserve the heavily damaged burial site of Otto the Great, the 10th-century ruler who laid the foundations of the Holy Roman Empire.

Excavations uncover clues to the tomb’s history

The relocation of the sarcophagus also allowed archaeologists to investigate its foundation for the first time. Excavations revealed large sandstone blocks beneath the tomb, including reused building stones marked by late medieval stonemasons. The findings suggest that the sarcophagus was moved several times over the centuries.

Excavations produced numerous artifacts, including coins, glass beads, ceramics, roof tiles, clothing pins, and fragments of painted plaster from earlier cathedral structures. Researchers also uncovered a lead bullet beneath the floor, reflecting Magdeburg’s turbulent history.

Researchers also uncovered layers of rubble linked to medieval and early modern construction activities in the cathedral’s High Choir. A network of underground passages, some possibly dating to the Middle Ages, was also documented.

Despite the discoveries, archaeologists found no evidence showing whether Otto I’s tomb occupied the same location in an earlier cathedral that once stood on the site. The original placement of the emperor’s burial, therefore, remains uncertain.

Damage prompted conservation efforts

Otto I, who was crowned emperor in 962, established one of medieval Europe’s most powerful empires. His tomb in Magdeburg Cathedral is considered one of Germany’s most important medieval monuments.

The project began after routine inspections in 2024 revealed serious deterioration in the emperor’s tomb. Researchers identified several threats to the monument, including corroded iron fittings, rising moisture from the ground, and fluctuating humidity levels inside the cathedral.

Scientific analyses confirm the emperor’s remains

As part of the conservation work, experts carried out extensive non-invasive documentation of the sarcophagus and its surroundings. The marble cover slab, weighing about 300 kilograms (660 pounds), was removed so researchers could examine the damaged wooden coffin inside.

Anthropological and genetic analyses later confirmed that the human remains belonged to Otto I, supporting centuries-old historical accounts of his burial at the cathedral.

The emperor’s remains are scheduled to be reinterred on Sept. 1, 2026, in a newly designed coffin currently being created through a competition organized by the Saxony-Anhalt Art Foundation.

Restoration work addresses long-term damage

To protect the monument for the future, conservation teams moved the limestone sarcophagus from its original location in early 2026 using a specially designed transport structure. The sarcophagus now sits inside a secure enclosure within the cathedral, where restoration work is underway.

Specialists are removing corroded iron nails and clamps, many believed to date to the 19th century. As the metal rusted over time, it expanded and placed pressure on the stone, increasing the risk of cracking. Conservators are also removing harmful iron residues from the marble cover slab.

Cathedral remains open during conservation work

Church services continue as normal during the project, while visitors can still view major features of the cathedral, including the High Choir and its famous 13th-century sculptures. Officials said the public will continue to receive updates as restoration and research progress.

Archaeologists in Cyprus have uncovered a massive Late Roman wall at the ancient city of Amathous that may have formed part of a defensive system protecting the summit of the acropolis.

The structure, discovered on the site’s Western Terrace, offers new evidence of efforts to fortify one of the island’s most important ancient urban centers during the Late Roman period.

Details of the defensive wall

The wall reaches up to 2 meters (6.6 feet) in thickness and was built using large limestone ashlar blocks, smaller stones, and clay mortar. Excavation evidence shows that it underwent at least two construction phases, suggesting it remained an important feature of the acropolis over time.

Researchers also uncovered a floor surface associated with the wall, fallen architectural blocks, roof tiles, and mudbrick fragments from a collapsed structure. Together, the finds provide new insight into construction methods and defensive planning at Amathous during the final centuries of Roman rule.

The discoveries were made during the second excavation season of the French Archaeological Mission of Amathous, held from March 30 to April 24, 2026. The project is directed by Dr. Anna Cannavo and focuses on the Western Terrace of the Acropolis.

Expanded excavations reveal a substantial wall

The wall was first identified during excavations in 2025 following a geophysical survey conducted in 2024. During the 2026 season, archaeologists expanded Trench 1 and uncovered a much larger section of the structure.

The wall runs parallel to the natural edge of the terrace, with its southern section turning slightly toward the west. Its eastern face was constructed from large limestone ashlar blocks, while the interior was packed with smaller rough stones bonded with clay.

Researchers identified evidence for at least two building phases. The original wall measured about 135 centimeters (4.4 feet) in thickness. It was later strengthened by adding a second row of limestone blocks and filling the space between the two walls with stone rubble.

Foundations and associated floor date to the Late Roman period

A small trench excavated along the eastern side of the wall exposed its foundations and revealed a floor directly connected to the structure. Part of the floor was paved with reused roof tiles laid over a gravel bedding.

Excavation evidence indicates that both the wall and the floor date to the Late Roman period. East of the structure, archaeologists uncovered destruction deposits containing fallen ashlar blocks, roof tiles, and mudbrick fragments from the building’s upper portions.

Findings highlight the strategic importance of the Acropolis

A second excavation area, known as Trench 3, was opened at the northern end of the terrace. Although no architectural remains were found there, archaeologists recovered a rich collection of Iron Age artifacts, indicating earlier activity in the area.

Researchers believe the newly discovered wall formed part of a defensive system protecting the summit of the acropolis and the basilica that had replaced the sanctuary of Aphrodite, one of the most important religious centers in ancient Cyprus.

Future excavations will investigate the full extent of the fortification and determine whether the Late Roman remains were built over earlier structures, helping researchers better understand the long-term development of Amathous.

The beloved souvlaki has been around since ancient times. Archaeologists have found skewers dating back to the Bronze Age, and recent research looks at the functioning of early grills. In particular, “souvlaki trays” have been discovered dating all the way back to Mycenaean culture.

Therans and Mycenaean cultures were known for their luxurious lifestyles, ornate and colorful clothes, exquisite art, and sea trade with other cultures, such as Egypt. People developed these cultures on the islands of Crete and Santorini.

World’s oldest Bronze Age souvlaki on Santorini

The oldest souvlaki skewers found seem to be those discovered by archaeologists on Santorini dating back as far as 2000 BC. There are traces of the popularity of souvlaki on Santorini and Crete through the Bronze Age, and both Theran and Mycenean cultures made use of this method of cooking.

Ancient Greek texts such as the Iliad and the Odyssey describe a spit (Greek: ὀβελός) being used to roast meat, but the exact functioning of the souvlaki trays was unknown until recently. The works of great poets and writers describe the same obeliskos being popular. Sophocles, Aristophanes, Xenophon, and Aristoteles all mention or describe the popular dish in their works.

Mycenean cooking and culture

It seems that ancient Mycenaeans did not have a large variety of foods available to them. Despite this, they developed various types of cooking methods, fostering innovation. Part of that innovation was souvlaki trays, as was cooking in jars, among other techniques. At the time and for most of ancient history, cooking was mostly done on hearths with few ingredients. The portable and lightweight souvlaki trays changed this for Mycenaeans around 1400 to 1050 B.C.

Academics suggest that an important historical force behind these contraptions was status. While the Myceneans had incredibly rich art and fashion, their diet lacked diversity, though a marker of status was drinking wine. On the other hand, one can imagine poorer Mycenaeans drank beer.

As they were skilled sailors, Therans on Santorini island had begun brewing beer in the II millennium B.C., possibly learning the skill from Egypt or the Near East, where beer had been brewed since the III and IV millennium B.C. Accounts of the 5th and 4th centuries B.C. tell of an Athenian bias against beer. It was considered a drink of barbarians, Egyptians, or even women. Beer brewing was never seen as valuable.

By the Classical period, this all changed. Wine had become readily available to all, pushing elites in later Greek societies to seek other ways to distinguish themselves — for instance, through the use of specific gadgets and kitchen appliances, echoing earlier innovations like the Mycenaean souvlaki trays.

The souvlaki tray

The souvlaki trays found in Gla, Pylos, and Crete added something to the age-old tradition. Similar to modern-day outdoor grills, they were designed to be portable and good for travel or entertainment. Meat cuts seem to have been similar to the ones popular for souvlaki today, made from either lamb, pork, or mutton, and the meal was accompanied by bread made of various cereals.

The clay trays had placeholders for the skewers and, until recently, how they actually functioned was unknown. Researchers at Dartmouth College have recreated the trays using original ancient pottery techniques, tools, and ingredients. They realized the trays were not meant to be put on a hearth as originally thought. Rather, embers were placed in the tray and the skewers were grilled. They were practical, portable, and delicious!

Tourists stand in line under the summer sun outside Notre Dame Cathedral, waiting to climb the landmark and see its famous Roman artifacts. Just a few meters below them, archaeologists are digging into nearly 2,000 years of Parisian history.

The excavation is taking place beneath the cathedral’s forecourt as part of a project to redesign the square. Paris plans to add trees, shade, and cooling features around Notre Dame following its restoration after the devastating 2019 fire. Before work can begin, archaeologists must investigate and protect any remains buried underground.

French media have dubbed the project the “dig of the century” because of the discoveries emerging from one of the city’s most historic locations.

“It’s a rare opportunity for us to work on something that’s tangibly going to make a difference to the history of Paris,” Lucie Altenburg, a conservator with the Paris archaeology unit, told The Associated Press.

Ancient artifacts emerge

Researchers have already recovered hundreds of artifacts. One of the most important finds is a fourth-century coin depicting Roman Emperor Constantine. The coin was heavily corroded when it was unearthed, but X-ray imaging revealed the emperor’s portrait. Such finds help archaeologists date the different occupation layers beneath the cathedral.

The team has also uncovered fragments of medieval pottery marked with faint reddish inscriptions painted on the inside. Similar symbols appear on multiple shards, but experts have not yet determined their meaning.

Some of the most remarkable discoveries have come from medieval latrines buried beneath houses that once crowded the area around Notre Dame. The pits served as both toilets and rubbish dumps, creating conditions that preserved everyday objects for centuries.

Archaeologists have recovered complete jugs, cups, and other ceramics that survived intact after spending hundreds of years underground. It is “rare to find complete ceramics,” said archaeologist Valentine Breloux.

Clues to Paris’ evolution

The excavation has also revealed evidence of Paris’ transformation from the Roman city of Lutetia into the medieval capital that followed.

Archaeologists discovered a Roman stone doorstep that had been removed from a larger building, turned upside down, and reused as paving in a later roadway. The find shows how residents repurposed materials as the Roman world gave way to a new era.

Once artifacts leave the site, they are transported to the city’s archaeology center, where specialists clean, catalog, and study them.

Looking deeper into the past

The work is expected to continue as Paris moves forward with plans to plant 160 trees and create a cooler, greener public square by 2028. Archaeologists hope to dig even deeper before then, searching for traces of the Gauls, the people who inhabited the area before the Roman conquest.

“The hope is that we are able to go back in time even further than we’ve ever been before,” Altenburg said.
