The National Museum of the Cabildo and the May Revolution tells the story of the Spanish colonial rule in Argentina and the May revolution that ended Spanish supremacy in the country. It is a repository of government and revolutionary exhibits from the 18th century.
The Cabildo that houses the National Museum of the Cabildo and the May Revolution was a former residence of the Spanish Viceroy built in 1764. It became the city hall after Argentina declared independence from the Spanish Crown after the May revolution in 1810. The revolution took place in the Plaza in front of the Cabildo. It is one of the few colonial buildings still standing in Buenos Aires. Its original columns and facades were destroyed to make way for two major avenues and the present structure is the result of a reconstruction in 1940 based on the design of architect, Mario Buschiazzo.
Exhibits at the museum include paintings, artifacts, weapons, maps, documents, costumes, jewelry and photographs from the 18th century when the May revolution took place. An ornamental well constructed in 1835 is the only surviving part of the original Cabildo after the 1940 reconstruction. A crafts fair is held on Thursdays and Fridays in the courtyard.

The Participative Science Museum has few rooms but is packed with interesting things for children to do. It is run by the nonprofit Foundation of Science Museums and opened its doors in 1988. The focus of the interactive exhibits is to teach children and adults why things happen and what makes things happen. The goal is to make learning science and math enjoyable for children. The philosophy of the museum is touching each exhibit and learning while doing.
The Participative Science Museum offers enjoyable science tips and tricks for children and adults. Exhibits help children understand optics, natural, music, electricity, magnetism and electronics among other scientific disciplines. A popular exhibit is the, ‘Don’t Kill Me Math’ display which helps children understand the dreaded subject of mathematics using simple tricks. During the school year the museum attracts school children who are brought by their schools to learn from the interactive displays. Most of the exhibits are in Spanish and visitors who do not know the language may not enjoy the museum as much as bi- lingual tourists and locals.
