VIDEO: World War II mortar shell retrieved from deep cave in Hungary

An unexploded German mortar shell from World War II has been recovered from a depth of 60 meters inside the Vecsembükk Shaft cave, located within Aggtelek National Park, according to a Facebook post by the MH 1st Explosive Ordnance Disposal and River Flotilla Regiment.

Members of the Hungarian Cave Rescue Service discovered the extraordinary find in Hungary’s third-deepest cave during a rappelling training session. The 81-millimeter German mortar shell was lifted to the surface using rope access techniques in a complex operation carried out by bomb disposal experts, in collaboration with the cave rescue service and the Aggtelek National Park Directorate.

Warrant Officer László Török, commander of the bomb disposal patrol, confirmed the shell did not contain any explosives, posing no direct danger during extraction. It has since been safely transported to the Hungarian Defence Forces’ central collection site for further examination.

The discovery serves as a stark reminder that remnants of World War II combat equipment can still surface in unexpected places—even deep beneath the ground in caves. The Vecsembükk Shaft, one of the deepest in the country at 60 meters, yielded this historic relic from its depths.

Such findings are not only valuable for historical research but also critical for bomb disposal experts. The safe neutralization and removal of explosive devices is vital for maintaining public safety.
