In 2010, the Israel Antiquities Authority completed a two-month restoration and cleaning of Jaffa Gate as part of a $4 million project begun in 2007 to renovate the length of the Old City walls. The clean-up included replacing broken stones, cleaning the walls of decades of car exhaust, and reattaching an elaborate Arabic inscription erected at the gate's original dedication in 1593. Bullet fragments in the gate, from fighting in the 1948 Arab–Israeli war, were preserved. Infrastructure work beside Jaffa Gate also uncovered an ancient aqueduct dating from the 2nd or 3rd century AD.
