A lighthouse shaped like a windmill stands against a deep blue sky with a vibrant rainbow.

The image depicts a unique, cylindrical lighthouse shaped like a traditional windmill, featuring prominent white sails angled against a clear, deep blue sky. Situated on a stone pier, the structure possesses a clean, white facade with a dark, textured base. The lighthouse stands as the primary focal point, positioned towards the right side of the frame, overlooking a calm, dark blue sea that stretches across the bottom foreground.

A vibrant, semi-circular rainbow arcs across the left and center portions of the sky, casting a soft, ethereal glow against the intense blue backdrop. The atmospheric lighting creates a crisp, sunny day, enhancing the contrast between the white structure and the saturated blue tones of the water and sky.

The style appears to be a realistic photograph, capturing a serene, picturesque coastal scene. The composition is balanced, with the verticality of the lighthouse anchored by the horizontal line of the pier and the horizon, while the sweeping curve of the rainbow provides a dynamic visual contrast to the rigid architecture of the lighthouse.
