Which monument emphasizes the contributions of the Italian community in New Orleans?

The monument that highlights the contributions of the Italian community in New Orleans is Piazza d'Italia. This public square serves as a tribute to the rich cultural heritage and history of Italians in the city. Designed to reflect an Italian piazza, it incorporates architectural features that are reminiscent of Italy, such as classical columns and fountains, celebrating the influence of Italian immigrants in shaping New Orleans' distinctive culture. The Piazza not only serves as a gathering place but also symbolizes the pride of the Italian-American community and their significant impact on the city’s social and culinary landscape.

In contrast, the other options represent different aspects of the city's heritage. Tile Makers could refer to a craft or trade but does not specifically pertain to a monument dedicated to the Italian community. Margaret Gaffney Haughery was a notable figure in New Orleans known for her philanthropy and contributions to the orphaned and underserved, but she is not directly linked to the Italian community. Ocean Song may refer to a work of art or a location, yet it does not emphasize the Italian heritage specifically. Thus, Piazza d'Italia stands out as the dedicated monument celebrating the Italian community in New Orleans.
