Paraná, the capital city doesn't have a foundation act. It arose spontaneously as a consequence of the immigration from Santa Fe, the city placed on the other riverbank. About 1700 it was called Baxada.

Later on, it was called as the river that surrounded it "Paraná" that means "Sea Relative" in Guaraní language. The del Rosario Virgin image, arrived at the chapel in 1730.

Its most important dates were: 1854, it became the Capital City of the Confederación Argentina. In 1994, it became the opening session seat of the Constituent Convention, where the National Constitution was reformed.

The Paraná River ravines can reach 85 meters height, that is why they are a natural viewing point. The city streets are full of old trees and there are a lot of fishing and sport boats on the river, so the landscape is a very peculiar one.

When the first inhabitants settled and the central area was consolidated different kinds of corridors were generated having very interesting viewing points. Paraná has very important old buildings. The cathedral, the government's House, the Centennial School, etc, would be the same if the environment that surrounds them was destroyed. The "paranaense" architecture can be divided into several periods:

• From 1730 to 1850: colonial architecture
• From 1850 to 1880: the Confederation architecture
• From 1880 to 1910: the Liberalism architecture
• From 1910 to 1940: the elegant architecture
• From 1940 to 1960: rationalism and nationalism
• From 1960 to 1980: modern movement.

It is represented by the splendid housings that belonged to the economically consolidated bourgeoisie. The example was Buenos Aires City bourgeoisie, this fact would be repeated along history. There was a changing of the Italian style by the French one. There were a lot of marquees, and staircases. The facades were made of stony materials, in soft neuter colors without academic rigidity.
