Porta Adriana, Renaissance city gate in Ravenna, Italy

Porta Adriana, also called Port'Aurea Nova, stands at the west end of Via Cavour near Piazza Baracca. The current gate was built in 1582–1583 for Cardinal Guido Luca Ferrero, replacing an earlier gate first documented in the 11th century beside a canal from the Po. Its decorative marbles were taken from the demolished Port'Aurea.

A gate already appears in 11th-century maps, beside a canal fed by the Po and on the route linking Adria and the Adriatic; its name comes from a medieval aristocratic family. The present building was begun in 1582 for Cardinal Guido Luca Ferrero and finished the next year, with an epigraph lost and put back in 1904. It was also called Port'Aurea Nova because decorative marbles came from the recently demolished Port'Aurea. Cardinal Domenico Rivarola restored the inner facade in 1615, and work followed Pius IX's 1857 visit.

The gate's name comes from an aristocratic family of the Middle Ages, while its second name, Port'Aurea Nova, recalls the decorative marbles taken from the demolished Port'Aurea and reused here. The inscription placed in 1583 was lost and put back in 1904.

Porta Adriana stands at the western end of Via Cavour, beside Piazza Baracca, on the edge of Ravenna's historic centre. Coming from the station side, it is the first gate you meet on foot along Via Cavour. The inner facade faces the city; the outer side looks toward the former moat line.

The gate's second name, Port'Aurea Nova, comes from the decorative marbles taken from the demolished Port'Aurea and reused here in 1582–1583. The inscription commemorating the work disappeared and was put back in place only in 1904.
