The image displays a detailed view of the upper facade of the Siena Cathedral (Duomo di Siena) in Siena, Italy, under an overcast sky. The central feature is a large, ornate Gothic gable culminating in a statue of a winged angel holding a trumpet at its apex. Below this angel, a prominent triangular mosaic, "The Coronation of the Virgin" by Luigi Mussini, depicts religious figures, including a central figure with a halo, surrounded by numerous angels and saints, against a radiant gold background. This mosaic is framed by a highly detailed border featuring numerous smaller architectural elements and sculptural figures. Directly beneath the mosaic is a wide, horizontal band of intricate white and pinkish marble carvings and smaller niches containing individual statues. Centered below this band is a large, circular rose window, divided into multiple rectangular panes by a dark grid. The window itself is framed by an elaborate, sculptured surround featuring additional figures and decorative motifs. Flanking the central gable and rose window are sections of vertical architectural elements, including pilasters and buttresses adorned with intricate carving, Gothic finials, and visible gargoyles. Numerous statues of human figures are integrated into the facade's various horizontal and vertical decorative tiers. The overall construction is characterized by multi-colored marble (white, dark red/pink, and grey), showcasing elaborate Gothic ornamentation and sculptural work.
