Crown of Seven Weathers

A monumental civic weather instrument formed by seven unequal rigid towers on a broad ring-shaped pearl-cloudstone dais around an open central sky well. Their inward-leaning tips create a complete crown silhouette while remaining seven distinct buildable machines: a framed amber sun petal, a blue-ice rain basin with copper cups, a layered coral-gold-blue rainbow fin, a blackened-copper lightning fork with ceramic beads, a rigid vapour vane, a raised blue-ice lens, and a calm-air bell. A ceremonial stair enters from front +Z through a deep oval gate. Heavy cloudstone ring segments alternate with open prism-screen loggias on slender spun-glass columns. Copper ribs and splayed pumice buttresses support the towers, while a stepped rear service arcade preserves visible grafted machinery. Deliberate glass-stitched scars mark every outer side. Resolve the inner sky well, outer ring, entrance stair, rear arcade, tower fronts and backs, loggia depth, projecting platform undersides, roof surfaces, openings, and supports.
