In the Spanish Colonial architecture there was a main plaza surrounded by the most important buildings, and the city was organized in a grid of squares.

Carmen de Zabalía, granddaughter of Francisca Bazán and Nicolás Laguna, inherited the house in 1839 and began works to restore it.

The humid climate of Tucumán and the materials used to build it caused a fast deterioration, and the family did not have the money to properly maintain it.

President Julio Argentino Roca, native of Tucumán, authorized a project to demolish the outer building and enclose the hall into a structure that would protect it from the climate.

The national representative for Tucumán Ramón Paz Posse sent a bill to the Congress proposing the reconstruction of the House in its original form.

The new walls were made with bricks instead of adobe, the reeds of the roof were tied with leather, and the doors were not painted at the moment for the lack of documentary evidence of their original color.

[7] President Juan Domingo Perón declared the economic independence of the country in the house on July 9, 1947, after the complete payment of Argentina's external debt.

The annual celebration of the declaration of independence is attended by the president of Argentina, the governor of Tucumán province, their cabinets and special guests.

The show ends with the national anthem in front of the Argentine flag, flanked on either side by large reliefs of the historic scenes sculpted by Lola Mora.
