Sobre a floresta 

"Sobre a floresta" (About the Forest) is a sculpture by Portuguese artist Alberto Carneiro, known for his minimalist and monumental works. The piece features a series of tall, slender granite columns arranged in a grid-like formation, evoking a forest. The bare branches of the trees, sculpted from metal, contrast with the smooth, solid columns, suggesting both the fragility and resilience of nature. Carneiro's work often explores themes of space, time, and the relationship between humans and the natural world.
