The Mud Museum was founded in 1979 as a private institution. It is also known as the clay museum, because much of its collection is the clay and mud pieces made by indigenous people.
Currently the heritage of the Mud Museum consists of more than 4,000 pieces corresponding to mestizo productions from the 17th century onwards. These works include wood carvings, fabrics, lace, ceramics and goldsmiths. The museum also includes a collection of 300 pieces of pre-Columbian pottery from all over the Americas.
The collection is constituted on the basis of pieces acquired by Carlos Colombino over twenty-five years. On this basis, the collection grew with the contribution of works donated by Osvaldo Salerno and other individuals and institutions and pieces acquired later with the funds of the Foundation, legal platform of the CAV / MdB.
