Plaza Italia, Cultural heritage square in Lima District, Peru.

Plaza Italia is a historic square in Barrios Altos, Lima, featuring stone pavements and traditional architecture spanning different periods. Multiple streets intersect at this location, and the area combines architectural elements reflecting the neighborhood's layered past.

During colonial times the square was called Saint Anne's Square and later became one of four locations where Peru declared independence. The name was subsequently changed to reflect the influence of Italian immigrants on the neighborhood's growth and character.

The name comes from the Italian community of Barrios Altos, whose pulperías and bodegas lined the surrounding streets in the mid-19th century. The Italian colony promoted a monument to naturalist Antonio Raimondi, a neighbour of the area, made by sculptor Tancredi Pozzi and finished in 1914. Nearby stand the churches of Santa Ana and San José, and two closed cinemas, the Pizarro and the Unión.

The square sits at block 7 of Jirón Huanta, between Jirón Junín and Jirón Huallaga, in Barrios Altos. It is a short walk from the Palacio del Congreso, the Mercado Central and the Chinatown, and about a block from the Casa de la Moneda and the Piedra Horadada. The paving is small cobblestones with a smoother, lighter path across it, so watch your footing.

The monument to Antonio Raimondi, a neighbour of the square, was made by sculptor Tancredi Pozzi and inaugurated in 1914, the same year the name Plaza Italia was finalised. The square had been known as Plaza Santa Ana after the hospital and church of Santa Ana; the hospital moved in 1924 to become the Hospital Arzobispo Loayza.
