Ice Architecture

Create a story around an ancient civilization that only built in ice and what remains of their icy edifices in modern times.

Using the element of ice, explore a civilization that only used frozen water as their construction material. Dig deeper into their architectural marvels, the social setup, and the challenges they faced. How does the modern world look at these icy remnants? This prompts aids in building a backstory, contrast between past and present, and understanding permanence and impermanence.
