Museo de Gallo is the largest Art Brut Museum in Cuba. This exceptional open-air museum is the work of Héctor Pascual Gallo Portieles who has an interesting past.

Born in Havana in 1924, Héctor Pascual Gallo Portieles began working as a barber's apprentice at the age of 12 when his father was deposed of governership and his family faced financial hardship. Shortly before the revolution, he took part in the calendestine action against the bloody Batista regime. Thus, he was appointed commercial representative to Paraguay by the newly formed government after the victory. However, his primary role was as a covert security agent. A semi-literate Hector Gallo served in 20 countries as a diplomat. While ambassador to Cambodia, he abandoned his profession at the age of 58 to pursue writing and giving lectures.

His retirement and the cessation of Soviet aid plunged Héctor Gallo into severe financial hardship. His pension was not enough even to eat. Consequently, he was forced to leave his spacious apartment flat in Vedado for a small apartment in neighborhood of Alamar, in the outskirts of Havana.

Hector Gallo, who was 65 years old and had no motivation left, managed to hold on to life by devoting himself to art. He began collecting unused, abandoned objects of various sizes and materials, creatively combining them to unique objects. He placed the newly formed objects in his garden, giving them as though a second life. This led to the creation of El Jardin de los Afectos (the Garden of Love). He placed smaller objects throughout his home, which he called La Galeria. Soon, the entire garden, his apartment, and even the adjacent sidewalks were filled with all manner of incredible objects. He transformed items such as typewriters, sewing machines, old televisions, and other discarded materials into stunning art pieces while breathing new life into these objects. According the philosophy of Hector Gallo the life is not but a permanent transformation of the matter and that is what makes it eternal.

Hector Gallo's works were exhibited in Havana in 2014 and 2016.
