Torso do Trabalhador ("Worker's Trunk") - Sculpture of paranaense artist Erbo Stenzel (1911-1980), cast in bronze and placed inside the glasshouse, in a fountain. This sculpture was made in 1941 and was placed in 1994 to honor all the workers of the world, when Curitiba hosted the "World Habitat Day" in 1995 - an event celebrated by UN to make reflection on the situation of cities and the human right to adequate housing, as well remind the world of its collective responsibility for the habitat for future generations.
