The Antica Porta San Donato is a gate to the ancient walls of Lucca that faces west. It was established in 1590 and remained in operation for about 50 years when it was replaced by the new Porta San Donato between 1629 and 1639. It is located in the current city walls of Lucca, in Piazzale Verdi.
Today the structure is home to the tourist information office in Lucca.
