This vibrant cityscape captures a grand promenade at sunset, with classical architecture dominating the scene. Tall white columns line the left side of a broad walkway, casting long shadows across the marble pavement. A magnificent domed building with golden cupolas stands prominently in the background, its white facade glowing in the evening light. The sky is rendered in deep, rich blues, creating a dramatic contrast with a fiery orange sunset visible at the horizon. Small figures stroll along the walkway, their elongated shadows stretching across the ground. The painting employs a strong sense of perspective, drawing the viewer's eye down the colonnade toward the dome. The overall color palette is dominated by blues and whites, with strategic touches of gold and orange that emphasize the transitional moment between day and night. The brushwork appears loose and expressive, particularly in the sky and architectural details, creating a dreamlike quality that suits the painting's title.
