In Sofia, Bulgaria, a large yellow drilling rig stands on a construction site

In Sofia, Bulgaria, a large yellow drilling rig stands on a construction site. The rig, with its tall mast and mechanical arm, is positioned in the foreground, dominating the central portion of the image. Behind the rig, a line of lush green trees partially obscures several multi-story buildings with red tile roofs. These buildings appear to be older structures, possibly residential or institutional. In the background, rolling, tree-covered hills rise under a clear blue sky dotted with a few white clouds. A cylindrical metal object, possibly a pipe or casing, lies on the ground to the left of the drilling rig. The ground of the construction site is a mix of gravel and dirt, with some scattered debris and fencing visible. The overall scene suggests active construction work in an urban area with natural surroundings.
