MAL093 - Taht l-Irdum


Taht l-Irdum are a series of salt pans, located in southern Malta, on the western peninsula of ll-Ponta ta’ Delimara, within Marsaxlokk. The site is not accessible to the public as it can be reached via a flight of stairs through a gated passageway. The salt pans cover an approximate area of 6,080m2.. The salt pans are still being used for salt harvesting due to the presence of industrial equipment for the hoisting of harvested salt on the overlaying cliff face. The harvested salt is stored in rooms adjacent to the hoisting equipment. The site is predominantly surrounded by natural habitat and a series of derelict structures. Kalanka Lighthouse is also located within a close proximity of the site. No vegetation was present growing within and around the site. The salt pans area classified as an Area of Ecological Importance under G.N. 400/96 and Area of High Landscape Value under G.N. No. 903/15 – GF 124/08 due to the presence of coastal cliffs. The site is within a No Trapping Zone under S.L 504.71.
