The Piazza d'Italia is an urban public plaza located at Lafayette and Commerce Streets in downtown New Orleans, Louisiana. It is controlled by the Canal Street Development Corporation (CSDC), a subdivision of New Orleans city government. Completed in 1978 according to a design by noted postmodern architect Charles Moore and Perez Architects of New Orleans, the Piazza d'Italia debuted to widespread acclaim on the part of artists and architects. Deemed an architectural masterpiece even prior to its completion, the Piazza in fact began to rapidly deteriorate as the development surrounding it was never realized. By the turn of the new millennium, the Piazza d'Italia was largely unfrequented by and unknown to New Orleanians, and was sometimes referred to as the first "postmodern ruin".
