Archaeologists from the Intercisa Museum found the limestone altar while surveying the riverbed near Szalki Island. Diving archaeologist Attila J. Tóth also took part in the work.
The team began the survey after the river fell far below its usual level. Large parts of the riverbed, normally hidden underwater, became reachable for the first time in years.
The archaeologists had hoped to find remains linked to the presumed medieval Pentelic Monastery. Instead, they found a fragment of a Roman altar dedicated to Jupiter, the chief god of the Roman pantheon.
A few days later, the team recovered two fragments of inscribed limestone tablets from the same area. Together, the finds add to the growing group of Roman remains from the river around Dunaújváros.
The ancient settlement of Intercisa once stood at the site of modern Dunaújváros. A Roman military fort formed the center of the settlement, which stood along the Danube frontier in the province of Pannonia.
Intercisa was part of the Roman Limes, the network of forts, roads, walls, and other sites built along the empire’s borders.
Roman altars dedicated to Jupiter often came from soldiers, officials, or private people fulfilling religious vows. Inscriptions on such altars and stone tablets sometimes record names, military units, or dates.
Such details help archaeologists study life at Roman frontier sites and trace the people who lived and served there.
The new finds also add to the known Roman monuments from Intercisa. Museum staff expect further study of the stones to provide more information about the settlement and its religious life.
The unusually low river also exposed a much more recent object. During the survey, museum staff found what they believe is an unexploded World War II munition.
The object led to an immediate call for military bomb disposal specialists. The find highlights the risks of searching newly exposed parts of the riverbed.
Museum staff have warned people against collecting artifacts from the exposed areas. Such activity could damage archaeological remains and expose people to unexploded wartime ordnance.
Anyone who finds a suspicious object should leave it where it is and contact the authorities.
Low water levels along the Danube have exposed archaeological remains in several areas in recent years. At Dunaújváros, the retreating river has now revealed Roman evidence from Intercisa alongside hazards from the 20th century.
