Shells on the beach and tower

Shells on the beach and tower is a castle, fort or tower in Na h-Eileanan Siar, Scotland. Perhaps the shells are not decoration but a warning, a reminder that the sea reclaims what pride builds. Maybe the tower stood where a shipwreck repeated itself, spitting brass and bone onto the sand until someone built a chamber to contain the noise. Imagine climbing its stairs at low tide and hearing every drowned voice still arguing about the route home.
