large, abstract sculpture composed of stacked rectangular blocks of granite and rust-colored metal

large, abstract sculpture composed of stacked rectangular blocks of granite and rust-colored metal. The sculpture is situated outdoors, with lush green trees and foliage forming the background. The granite blocks are light gray and speckled with dark flecks, while the metal blocks have a textured, oxidized surface. Some of the metal blocks exhibit a reddish-brown patina, suggesting they are made of rusted steel. The blocks are arranged in an asymmetrical, tiered composition, with some blocks appearing weathered and showing signs of plant growth. In the foreground, a large, flat granite block rests on a lower base. Wooden elements, possibly benches or structural supports, are visible beneath some of the blocks. The lighting suggests a bright, sunny day. The sculpture is located in the area of the National Palace of Culture in Sofia, Bulgaria. There are no people or animals visible in the image.
