Archaeologists have uncovered the ruins of a 2,000-year-old temple believed to have been built by an ancient civilisation featured in Indiana Jones. Remains of ancient altars and inscribed marble slabs were discovered submerged underwater along the Italian coast, near Naples, having likely laid undisturbed for millennia.

The religious temple was located off the coast of Puteoli, which is modern-day Pozzuoli, and is thought to be the first known temple discovered that was built by the Nabataeans outside of the Middle East.

Discovery Channel’s popular show “Expedition Unknown” was recently on site to document the discovery of 12 human skeletons and artifacts dating back at least 2,000 years, which had all been long hidden beneath the famed Khazneh (or “Treasury”) in Petra. The colossal find was accomplished by a team lead by archaeologist Pearce Paul Creasman.
