The Cabildo is an iconic building in Buenos Aires and a key historical symbol, the site of the May Revolution of 1810 and the seat of Argentina’s first patriotic government.
Built in 1580 as the center of colonial administration, it has been renovated several times but retains its historical significance.
Today, it houses the National Historical Museum of the Cabildo and the May Revolution, displaying objects and documents from that era.

The 25th of May is a very important national holiday in Argentina — it’s known as “Día de la Revolución de Mayo” or May Revolution Day.

What does it commemorate?

It marks the May Revolution of 1810, which was the beginning of Argentina’s path to independence from Spanish rule. On May 25, 1810, a group of local leaders in Buenos Aires ousted the Spanish viceroy and established the Primera Junta, the first independent government in what was then called the Viceroyalty of the Río de la Plata.

This event is considered the birth of the Argentine nation, even though full independence wasn’t declared until July 9, 1816.

A traditional dish that Argentine families often prepare for this commemorative day is Locro.
Locro is a hearty stew made with a base of white corn and white beans, slow-cooked with a variety of meats including pork (such as ribs, skin, and bacon), beef flank, and sausages — especially chorizo criollo and chorizo colorado. It also features pumpkin or squash, which adds a creamy texture and helps balance the richness of the meats. Here’s a recipe:
