After months of repair, the scaffolding has been taken down from Jaffa Gate.  The restoration process included cleaning, filling gaps between stones, and replacing stones.  From Arutz-7:

The large black curtain covering Jaffa Gate, one of the two most famous gates leading in and out of the Old City of Jerusalem, was removed this morning at the official Jaffa Gate Rededication Ceremony. The celebrated large stone entrance underwent two months of preservation work, in the framework of a program to refurbish the Old City walls. The current walls of the Old City were built mainly by Sultan Suleimon of the Ottoman Empire in the 16th century. The current refurbishing work, which began three years ago, seeks to repair the damages of the ravages of time and neglect. At Jaffa Gate, large boulders and stones were strengthened, bullet marks were demarcated, designs and ornaments were restored, and the entire gate was cleaned.
