What is "ringwall"

Usage examples of "ringwall".

The ringwall looked like stone, perhaps once splashed molten, perhaps deliberately piled.

The Ringwall was an irregular polygon of mountainous cliffs, several kilometers across, above which the lower atmosphere seemed always to be hazy enough to blur detail.
