Tucumán
Tucumán, the Garden of the Republic. In its historic center beats the House where Independence was declared, in 1816. And within minutes, the peaceful city gives way to the yunga: a road that winds between forests and clouds up to Tafí del Valle, a paradise among mountains, of ancient menhirs and cheeses with history. Lemons, sugarcane, empanadas that are a national pride and the eternal voice of Mercedes Sosa. Tucumán cannot be explained: it must be lived. Tucumán is the homeland in bloom.

Natural wealth
The territory that defines it
Tucumán is the smallest province in the country and one of the most intense: within a few kilometers it goes from the sugarcane plains to the mountain rainforest and the peaks of the Aconquija, which exceed 5,000 meters. Its Yungas, green all year round, earned it the name of Garden of the Republic. Behind the mountains lie the Tafí valley, with its high-altitude meadows, and the Calchaquí Valleys, dry and luminous, from Amaicha to Colalao del Valle.

The mountain rainforest wraps the eastern slopes of the province: cloud forests, ferns, lianas and waterfalls that stay green all year and give Tucumán its name of Garden of the Republic. Minutes from the capital, the Sierra de San Javier, with the biological park of the Universidad Nacional de Tucumán, opens the forest to hikers and paragliders; further south, Aconquija National Park protects the complete gradient, from the rainforest to peaks above 5,000 meters.

After climbing the slope through the rainforest, the road opens onto a high valley at about 2,000 meters, of green meadows, mountains and the waters of the La Angostura dam. It is the land of the menhirs of the Tafí culture, of estancias of Jesuit origin, such as La Banda, now a museum, and of a centuries-old cheesemaking tradition celebrated every year at the National Cheese Festival.

Human wealth
The living figures
Tucumán is the cradle of Independence: Argentina was born in its Historic House. Its identity blends the Diaguita heritage of the valleys with the culture of the sugar mill and the harvest, which for more than a century shaped the life of the province. At the table, the Tucumán empanada reigns, with its knife-cut filling and its own national festival in Famaillá, alongside quesillo cheese and the sweets of the valleys. And in music, the zamba and the chacarera found some of their greatest voices in Tucumán.
- More than 2,000 years ago · farming peoples of the Tafí valley raise the menhirs: about 50 carved stones up to three meters high, now gathered in El Mollar
- 16th and 17th centuries · the Quilmes, a Diaguita people, resist the conquest from their city in the Calchaquí Valleys, the largest pre-Hispanic settlement in the country. In 1667 they are defeated and exiled on foot to the outskirts of Buenos Aires, where the city that bears their name stands today
- 1565 · San Miguel de Tucumán is founded in Ibatín; in 1685 it moves to its current site
- 1812 · the Battle of Tucumán, decisive in the War of Independence
- 9 July 1816 · the Congress gathered in the Historic House of Tucumán declares Argentine Independence

In the house of Francisca Bazán de Laguna, the Congress declared Independence on 9 July 1816. In the early 20th century everything was demolished except the Hall of the Oath, which was protected inside a French-style pavilion: that contrast gave rise to the nickname "the Little House of Tucumán". Declared a National Historic Monument in 1941, it was rebuilt in 1943 by the architect Mario Buschiazzo on its original foundations, based on a photograph taken by Ángel Paganelli in 1869.
Today it houses the Museo Casa Histórica de la Independencia. Since 1992, every 9 July Tucumán is the capital of the Republic and the House hosts the main ceremony for Independence Day.

The first Argentine dairy product with a Geographical Indication, recognized by Resolution 31/2026 of the Secretariat of Agriculture, after more than 20 years of work by the Universidad Nacional de Tucumán with the producers. It is made with cow's milk from herds in Tafí del Valle and El Mollar, aged for at least 30 days. Its tradition dates back to the Jesuits of the 18th century, and among its historic producers is Estancia Las Carreras, home of the well-known M cheese.
