An image taken on an overcast day depicts a multi-story high-rise building under construction in Sofia, Bulgaria. The lower and middle sections of the building are partially clad with a dark blue or grey glass curtain wall facade featuring a grid of rectangular windows. The upper section of the building remains an exposed concrete and steel structural skeleton, indicating ongoing construction. A yellow tower crane is positioned atop the unfinished concrete structure, its jib angled upwards and to the left, static. The background consists entirely of a uniformly grey, cloudy sky. No individuals, discernible actions, or interactions are visible. This structure is identifiable as part of the Millennium Center complex, situated at the intersection of Bulgaria Boulevard and Vitosha Boulevard.
