Gold and silver Celtic coins, Baltic amber, glass objects, mirror fragments and metal vessels were found near Hradec Králové, where archaeologists uncovered an unusually large La Tène settlement along the route of a planned Czech highway.
The discovery was reported by the Museum of East Bohemia in Hradec Králové, whose archaeologists worked with the University of Hradec Králové and Archaia Praha. The museum described the site as exceptional for Bohemia because of its size, preservation and range of finds. It dates to the La Tène period, the Iron Age culture often associated with the Celts.
The site came to light during survey work for the future D35 highway. According to the Czech Center Museum Houston, archaeologists first identified it in 2023 while examining land for the road project, then continued excavation over the next two years. Lead archaeologist Matouš Holas told Czech Television that the first artifacts made clear the team had found something large. He also said the settlement likely would have remained hidden if the highway work had not taken place.
A 25-Hectare Site Under the Route
The settlement covered about 25 hectares, or 62 acres, near Hradec Králové in northeastern Bohemia. That scale makes it far larger than most Iron Age sites in the area, which the Czech Center Museum Houston said usually measure only 1 to 2 hectares. Its size, dense remains and rich material finds led experts to describe it as one of the largest Celtic sites in Central Europe.
The Museum of East Bohemia placed the settlement’s peak in the 2nd century B.C., before the rise of oppida. Oppida were large fortified centers, but this site appears to have become important earlier and without defensive walls. The museum said its significance may be comparable to major central settlements known from the Middle Danube region and southern Germany.
That lack of fortifications is one of the site’s clearest surprises. Archaeologists found dwellings, production areas and probably one or two sanctuaries, but no defensive enclosure. The evidence does not show whether the community faced conflict. What it does show is a settlement shaped by craft work, exchange and possible ritual activity rather than by visible military defenses.
Coins and Amber Point to Long-Distance Trade
The finds included gold and silver coins, coin dies, pottery fragments, dwelling foundations, production areas and many metal objects. The museum described the settlement as a supra-regional trade and production center connected to long-distance routes. Amber, precious-metal coins and evidence for high-quality ceramic production all support that reading.
The Czech Center Museum Houston listed coins of different sizes, jewelry, amber, glass, pottery, ceramics, mirror fragments and metal vessels among the recovered objects. It said the small coins are thought to have been modeled on Roman coins from the same era. Tools and workshop remains also suggest that artisans from several trades lived and worked at the site.
The scale of the material is striking. The Czech Center Museum Houston reported that archaeologists had collected 13,000 bags of artifacts, while the Museum of East Bohemia later gave a figure of 22,000 bags of finds, including everyday objects and rich jewelry collections. Those different totals appear to reflect different stages of excavation or cataloging. In either case, the site produced an unusually large archaeological collection.
Amber gives the discovery its wider map. The Czech Center Museum Houston said the presence of Baltic amber led experts to connect the settlement with the historic Amber Trail, which linked the Baltic region and the Mediterranean world. The site has also been discussed in relation to luxury goods known from the Baltic amber trade network and the work of Maciej Karwowski, an archaeologist at the University of Vienna.
Unusual Preservation Kept the Record Intact
The Museum of East Bohemia said the site stands out not only for its finds, but for how much survived in place. Archaeologists were able to examine La Tène occupation layers that had been little disturbed by intensive farming or illegal metal detecting. That gave the team a stronger record than they would have had from scattered objects or looted metal finds.
The topsoil held an unusually dense concentration of material. According to the museum, the original settlement surface preserved in the plowsoil and subsoil carried more information than is normally expected, and even more than the fills of deeper archaeological features. Put simply, the upper layers of soil kept a detailed trace of how people used the settlement.
That matters because the discovery is not just a cache of impressive objects. Coins, tools, pottery, dwelling traces, production areas and possible sanctuaries together show a working community. People lived there, made goods, handled valuable materials and may have gathered in spaces with religious or ceremonial meaning.
The Builders Are Still Debated
The Czech Center Museum Houston connected the site to the Celtic roots of Bohemia and said experts believe it was most likely built by the Boii, the Celtic people traditionally linked to the name Bohemia. It also cited the Czech historian František Palacký, who described the Boii as the first group to inhabit Bohemia.
That link remains cautious rather than settled. Tomáš Mangel, an assistant professor at the University of Hradec Králové whose work includes Iron Age and settlement archaeology, has studied the archaeological record of this period. The available sources connect Bohemia with the Boii as a traditional association, while treating the exact identity of the settlement’s builders with caution.
The settlement appears to have disappeared around the 1st century B.C.E. The Czech Center Museum Houston said there is currently no evidence pointing to violent conquest by neighboring peoples, and that economic or environmental reasons may have played a role in its decline. The same source said excavation is complete for now, while cataloging and analysis of the artifacts continue.
