MODERN MOVEMENT

Urban Planning In 1963-1964 Juan Parrochia, architect and urban planner, at the request of the Junta de Adelanto team, developed a Sectional for lower Chacal- luta, where he also designed the architecture and zoning of Club Hípico (Equestrian Club). In 1968, architect and urban planner Emilio Duhart, commissioned by CORMU and aware of the explosive population growth (18,947 inhabitants in 1952 to 80,667 in 1970) and urban expansion over many years, executed a project to turn Arica into a modern metropolis. This considered a structure and level of motorization that included large traffic circles -one of them with an underpass-, six-lane avenues, ring roads, industrial roads, port expansion, and an international airport.

Central Arica Sectional Plan, 1971 Architect: Emilio Duhart

Between 1953 and 1976, the city of Arica was the axis of a political, legal, and strategic project that, through a series of laws and decrees, transformed its geopolitical situation. The economic plan designed by the administration of Carlos Ibáñez del Campo sought to provide a strong stimulus for work and production, consolidating the state as the promoter and manager of economic progress. The objective was, according to historian Paulo Andrade, to consoli- date the “inward-looking” model, that is, to replace imports, reduce eco- nomic dependence on foreign countries, and create a national industry to, among other things, satisfy the demand of the domestic market and create a process of mobility and immigration that would improve living standards and reduce the high unemployment rates using this model. Among the laws and ordinances involved in this process, one of the most important was Supreme Decree Number 303, enacted on July 25, 1953, which granted the city the status of a Free Port and exempted it from customs duties and taxes. It also had a decentralized agency, created by law, which was intended to finance projects aimed at promoting social and economic development. This entity was created under the name of Junta de Adelanto de Arica. In 1958, it was an outstanding example and lasted until 1976, when the Law was repealed. “Arica was presented as an important moment in modern Chilean architecture during that process of economic and urban development. Its geographical conditions, desert landscape, and lack of rainfall, were unique opportunities for the birth of a particular landscape, which beyond its volume or quantity, was important for its great architectural quality, or its density, at a critical moment in architecture” (*). The laws and special decrees that promoted the development of Arica were one of the most visible expressions of the political effort to turn it into an exemplary city, and it explains why the traces of outstanding architects and planners have made it possible to place an intermediate city, far from the center of power and bordering the city, at the forefront of urban and architectural innovation in the country.

The project coincides with the free plan principles and the idea of the architectural envelope, proposing a stereometric steel structure, with a truncated pyramidal shape and an opening at its apex. The material used was a copper and steel alloy for greater durability. It was supported by an exposed reinforced concrete perimeter wall. Two portals created level pedestrian accesses and “to the south, a series of concrete canopies were designed to cover the entrance and exit of passengers,” recalled architect De Carolis in an interview in 2024. Another remarkable access was in the form of a periscope towards the public space. The interior program was resolved with offices on its perimeter and an illuminated plaza in the center, which included retail and subterranean restrooms.
