The world's oldest hunting traps may consist of four massive stone constructions.

Four enormous stone funnel systems that archaeologists have discovered provide the most convincing proof of extensive prehistoric hunting traps in Europe to date.

Early European towns were represented by their size and design as being able to plan coordinated, landscape-wide hunts long before such infrastructure was considered feasible.

Across the limestone uplands of the Karst Plateau, a rocky terrain that spans the present-day boundary between Italy and Slovenia, the constructions resemble enormous stone funnels. The purpose of the funnels seems to be to direct animal movement toward hidden endpoints.

Dimitrij Mlekuž Vrhovnik and colleagues at the University of Ljubljana identified these formations as intentional creations rather than natural features after they were discovered through aerial imaging.

Long, low walls that converge into sunken enclosures over hundreds of meters are preserved in each work. The buildings have a recurring and consistent architectural design.

The question of when these systems were initially constructed remains unanswered by the data, allowing for a more thorough analysis of their social and historical background.

Sheep-steering walls

Once you know where to look, it's difficult to overlook the long guiding walls that formed funnels due to their enormity. With surviving crests frequently close to 20 inches (50 centimetres), builders built limestone into lines that were roughly 3 to 5 feet (0.9 to 1.5 meters) broad.

Each funnel ranged in length from roughly one-third of a mile to over two miles (0.5 to 3.2 kilometres) over the plateau. The walls were more effective as guides than as strong barriers because they were probably less than three feet (0.9 meters) high.

Hunting traps with hidden pits

The walls lead the animals to a deep corral beneath a rocky ledge or cliff at either narrow end. The last drop occurred quickly because crews had set pens inside a doline, which is a hollow that resembles a sinkhole and is typical of limestone terrain.

Until the final 65 feet (20 meters) of approach, the cage remained hidden due to terrain breaks that obscured a clear view. Although its concealment might have prolonged a herd's composure, it also made the system dangerous to operate.

Without a timestamp, dating

Because stone walls don't leave many time stamps, it was more difficult to determine when the traps were erected than to find them. By determining age from carbon in charcoal discovered in a soil layer inside one pit, researchers employed radiocarbon dating.

The dates indicated abandonment rather than building since that layer developed after the walls were no longer in use. Despite that restriction, the data indicated that the system was already abandoned prior to the Late Bronze Age's transformation of the area.

Hunting traps constructed using group effort

The math highlights the fact that moving rock to construct guide walls over hills required more than weekend labour. The authors calculated that the greatest trap would require more than 5,000 person-hours of labour, which is far more than one household could afford.

Vrhovnik noted, "In either scenario, these installations reveal important aspects of prehistoric life: the fusion of animal ecology with architectural foresight, the transformation of landscapes into infrastructural systems, and the coordination of communal labour beyond the domestic sphere."

Planning, food sharing, and maintenance were all necessary for these undertakings, which forced the builders to take on responsibilities outside of their families.

When desert kites and Europe collide

Because the design resembled desert kites, which are big stone funnels used to capture herds, researchers were able to identify a silhouette on the map. Archaeologists have identified over 6,000 of these buildings across North Africa and Southwest Asia, many of which may be seen in satellite images.

While some research contends that specific kites assisted in the management and corralment of domestic herds, other sites are believed to indicate mass hunting of wild animals. Finding a near European cousin challenges preconceived notions about the proper place of such systems and extends that story into temperate regions.

Hunting trap-fitting animals

The plateau has peaks and valleys that funnel passage, and hunting traps only work when animals move in predictable ways. The scientists hypothesised that because red deer herds gather seasonally and use well-traveled paths, they would have been easy targets.

Local deer travelled in narrower, terrain-shaped pathways than desert gazelles, which may travel miles across open areas. The precise prey remains unknown and subsequent herding use cannot be ruled out in the absence of direct animal remains in the pits.

The reasons behind the construction of hunting traps by societies

Bursts of plenty can result from large community hunts, particularly when a society is able to process meat rapidly and distribute it broadly. The constructed environment kept the drive on course, and stone walls allowed hunters to guide animals as a team.

Cooperation would have been rewarded by success, as those who assisted in wall construction and repair also had access to the catch. Such a shared infrastructure suggests networks of trust, leadership, and regulations that are rarely seen in fragmented bones alone.

Fresh hints from the Karst

The stone walls on the Karst Plateau were preserved by slow erosion, leaving behind faint ridges that may still be seen on contemporary elevation maps. Even in rugged terrain, such micro-relief can be detected using airborne laser scanning, an aircraft survey that uses lasers to measure the form of the ground.

Archaeologists might discover that more huge hunting installations have been concealed in plain sight when other areas provide comparable data. Because simple coordinates can encourage theft or thoughtless harm, better maps can increase the stakes for site protection.

What archaeologists should do next

Organised hunting teams that altered regions of Europe are shown by funnel walls, concealed pits, and enormous labour. The hunting myth will be put to the test when future excavations link these structures to more precise dates and animal remains.
