« The people who forget their history are condemned to repeat it. »— Jorge Agustín Nicolás Ruiz de Santayana y Borrás, The Life of Reason, 1905
San Juan, on January 15, 1944, was devastated by a 7.4 magnitude earthquake. From Plaza 25 de Mayo, you observe the foundations of a new city emerging. It was here, in 1562, that Juan Jufré founded the city, and it is in this square that crucial reconstruction decisions would be made. Your investigation begins by examining the initial plans, comparing promises of modernity with the realities of the first construction sites. Every stone laid in this post-earthquake period bears the imprint of a strong political will from Juan Perón's government, which saw the catastrophe as an opportunity to create an innovative urban model for Argentina.
A few steps away, the San Juan Cathedral, rebuilt between 1952 and 1979, stands as a testament to this resilience. The original edifice, destroyed by the earthquake, gave way to a modernist structure. Your mission leads you to examine parish archives, where registers might conceal suspicious land transactions related to the acquisition of plots for the new street layout. The architects of the 1947 Regulating Plan had free rein to rethink urban planning, and rumors of expropriation and political influence abounded in post-war Cuyo.
Sarmiento's Birthplace, spared by the 1944 earthquake, contrasts with the modern constructions. This historic house, where Domingo Faustino Sarmiento was born in 1811, an emblematic figure of Argentine education and politics, is an island of old San Juan. Here you discover letters and documents that, although dating from the 19th century, reveal tensions between tradition and progress, an echo of the debates surrounding the "New City Plan." Sarmiento himself, in his time, did not hesitate to criticize abuses of power, a precedent that inspires your own investigation.
Parque de Mayo, inaugurated in 1910 and redeveloped after the earthquake, is a green lung strategically placed within the new urban plan. It is here that San Juan families gather, and it is often in public places that the most persistent rumors circulate. By analyzing the topographic maps of the era, you notice unexpected modifications in the alignment of avenues, suggesting compromises or arrangements. The nearby Museo de la Memoria Urbana preserves valuable oral testimonies that could confirm your doubts about the integrity of certain decision-makers of the time.
Your journey takes you past the Ex Banco Hipotecario Nacional, a building symbolizing the financing of this monumental reconstruction. Along Peatonal Tucumán, a vital artery of the city, you follow in the footsteps of the architects and workers who built this resilient San Juan. The path concludes at the Auditorio Juan Victoria, inaugurated in 1973, an acoustic masterpiece embodying the cultural and modern vision of the new city. You leave with an understanding of the economic and social forces that shaped San Juan, a city that, despite controversies, managed to rise from its ashes, offering a unique example of post-catastrophe urban planning in Argentina and the Cuyo region.
