The site of Moghar El-Taheen (or Moghr el Taheen), is an archaeological site brought to light at the beginning of the 20th century thanks to the photographs of the German Todor Vigan. His images showed a site whose surface had collapsed due to natural factors. It consists of a series of interconnected caves and tunnels displaying interesting geological forms, and several gates, basements, storage vaults and cemeteries cut into the white, powdery limestone rock, which gave the site its name. (Which translates to "flour cave" in Arabic).
In antiquity, the site was a stone quarry. Remains of extraction channels are still visible, as well as some holes dug in the rock, which were meant to facilitate the transfer of the blocks.
In Roman times, the site was used as a cemetery - an Arcosolia, in which the dead are buried under stone-cut arcades, in ornamental rock sarcophagi or coffins made of perishable materials.
During the 20th century, the inhabitants of the region used the site as an open dump, creating major environmental and hygienic problems.
The site has been completely cleaned and rehabilitated successfully within the framework of a project led by UN-Habitat and financed by the Italian Agency for Development Cooperation, in partnership with the municipality of Baalbek, the General Directorate of Antiquities, and the Lebanese Association for Coexistence and Development. It has become a historical tourist site, which the inhabitants of the region can also enjoy.
