Hidden beneath the present-day historical centre of Jerusalem lies a city built more than 3,000 years ago.

Every year it attracts more than half a million visitors captivated by its history. The entire extent of the archaeological site has not yet been fully explored. Our expertise as tunnel builders is required in order to proceed with the excavations and make the site accessible to the public. Excavation is carried out underground, manually (using a method referred to as ‘Marciavanti’), working closely with the scientists. The sensitive environment demands great dexterity and flexibility. Unexpected finds can lead to sudden changes in the direction of excavation, often accompanied by low overburden heights and difficult ground conditions.
