The image displays the grand nighttime entrance of the Palacio de Fontalba, located at Calle Serrano 15 in Madrid, Spain. The central feature is a large, ornate black wrought-iron arched gate, with its left panel slightly ajar, revealing the illuminated interior. Through the open gate, a red-carpeted grand staircase with white balustrades is visible, leading to an upper landing where a chandelier hangs. Two decorative planters containing floral arrangements flank the interior side of the entrance. The building's stone facade features elaborate architectural details above the archway, including decorative corbels and sculpted reliefs. Two black metal lantern-style wall sconces are mounted on the facade, one on each side of the gate, casting warm light. To the left of the gate, the address number "15" is affixed, below which a dark rectangular plaque is present. To the right of the gate, a circular bronze emblem, identified as the Royal Coat of Arms of Spain, is mounted on the wall. The foreground consists of a grey tiled sidewalk, illuminated by the building's exterior lighting. No individuals are present or discernible within the scene.
