Peruvian culture is primarily rooted in Amerindian and Spanish traditions, though it has also been influenced by various African, Asian, and European ethnic groups. Peruvian artistic traditions date back to the elaborate pottery, textiles, jewelry, and sculpture of Pre-Inca cultures. The Incas maintained these crafts and made architectural achievements including the construction of Machu Picchu. Baroque dominated colonial art, though modified by native traditions. During this period, most art focused on religious subjects; the numerous churches of the era and the paintings of the Cuzco School are representative. Arts stagnated after independence until the emergence of Indigenismo in the early 20th century. Since the 1950s, Peruvian art has been eclectic and shaped by both foreign and local art currents.

Argentine culture has significant European influences. Buenos Aires, considered by many its cultural capital, is often said to be the most European city in South America, as a result both of the prevalence of people of European descent and of conscious imitation of European styles in architecture. The other big influence is the gauchos and their traditional country lifestyle of self-reliance. Finally, indigenous American traditions (like yerba mate infusions) have been absorbed into the general cultural milieu.
