The Vilnius city wall was a defensive wall around Vilnius, capital city of the Grand Duchy of Lithuania. It was built between 1503 and 1522 for protection from the attacks by the Crimean Khanate at the beginning of the Muscovite–Lithuanian Wars. The stone and brick wall was a key element of the defensive system of Vilnius, and was paid for by the city's landowners. It contained nine gates and an artillery bastion.
