Goaboabanga

Possibly the most well-known goaboabanga in the world is that of Dezevau, depicted on its flag

Goaboabanga are an artform originating in Dezevau, characterised by additive metalworking and stoneworking and used for symbolic and self-expressive purposes. It can be considered a form of sculpture or handicraft, and is characteristically geometric and abstract rather than depictive. It is believed to have originated in the first millennium BCE, where goaboabanga were hung on trees and houses for superstitious, signage or decorative reasons; while this is still practiced, goaboabanga are also used in stylised form as symbols or emblems, as keystones on arches and in jewelry. Their modern name comes from the Ziba goaboa meaning "circle" and banga meaning "symbol", referring to their circular shape and their symbolism.
