Piazza d'Italia, Postmodern architectural structure in downtown New Orleans, United States.

Piazza d'Italia is an architectural structure in downtown New Orleans that occupies a city block behind the American Italian Cultural Center. The site displays curved colonnades, arches, and a fountain shaped like the Italian peninsula, blending classical orders with unexpected materials.

The Piazza d'Italia was built between 1977 and 1978 to a design by Charles Moore with Ron Filson and the Perez firm's Malcolm Heard and Allen Eskew, after New Orleans' Italian-American community proposed a memorial in the early 1970s. It deteriorated for years as the planned surrounding development never materialized. The conversion of the adjacent Lykes Center into the Loews Hotel was accompanied by a full restoration, completed by 2004.

The fountain is inscribed in Latin: on the left FONS SANCTI JOSEPHI, on the right HVNC FONTEM CIVES NOVI AVRELIANI TOTO POPULO DONO DEDERUNT, meaning the citizens of New Orleans gave this fountain to all the people as a gift. The plaza was conceived in the early 1970s by leaders of the city's Italian-American community as a permanent commemoration of the Italian immigrant experience.

The plaza sits at the corner of Lafayette and Commerce Streets and remains freely accessible during daytime and evening. Visitors can walk around the fountains and columns up close, with lighting effects most visible after dark.

The water jets were shaped as acanthus leaves, a botanical detail from Roman capitals. The combination of stainless steel columns and neon tubes creates an unusual dialogue between ancient forms and postwar light art.
