The six-month-long renovation of the Ka’abah has now been completed, as part of the largest ever expansion of the Two Holy Mosques. The Ka’abah, the focal point for one billion Muslims worldwide, needed renovation because the wooden pillars supporting it had decayed over the years. The three supporting columns and the roof have been completely rebuilt with sandalwood, and the stairs inside leading to the roof were reconstructed out of marble, together with the walls up to a height of three meters. The door of the Ka’abah, made of 270 kilograms of gold, was not touched, and was kept exposed for those worshipping, as was the Black Stone. Circumambulation (tawaf) continued as usual during the renovation, which did not in any way alter the dimensions of the Ka’abah.
