The Buenos Aires Cabildo is the public building in Buenos Aires that was used as seat of the ayuntamiento during the colonial times and the government house of the Viceroyalty of the Río de la Plata.
Currently, the Cabildo hosts the National Museum of the Cabildo and the May Revolution, in which paintings, artifacts, clothes and jewellery of the 18th century are on display. The patio of the Cabildo still has its 1835 ornamental water well.
