The building described is an impressive structure made of large grey stones stacked together. Despite its substantial and somewhat intimidating appearance, it has a unique quality that allows it to reflect sunlight beautifully, similar to how a dolphin's back glimmers in the morning light.

This vivid imagery highlights the contrast between the stone's heaviness and the light it catches, suggesting that beauty and elegance can emerge even from things that seem solid and unyielding. It encapsulates a central theme of the story, where true beauty lies beyond surface appearances.
