Fleur de lys metal wall art
Fleur-de-lis is a stylized lily (in French, fleur means flower, and lis means lily) or iris that is used as a decorative design or symbol. It may be "at one and the same time, political, dynastic, artistic, emblematic, and symbolic", especially in heraldry.
In building and architecture, the fleur-de-lis is often placed on top of iron fence posts, as a pointed defence against intruders. It may ornament any tip, point or post with a decorative flourish, for instance, on finials, the arms of a cross, or the point of a gable. The fleur-de-lis can be incorporated in friezes or cornices, although the distinctions between fleur-de-lis, fleuron, and other stylized flowers are not always clear, or be used as a motif in an all-over tiled pattern, perhaps on a floor.

It may appear in a building for heraldic reasons, as in some English churches where the design paid a compliment to a local lord who used the flower on his coat of arms. Elsewhere the effect seems purely visual, like the crenellations on the 14th century Mosque-Madrassa of Sultan Hassan.
Some modern usage of the fleur-de-lis reflects "the continuing presence of heraldry in everyday life", often intentionally, but also when users are not aware that they are "prolonging the life of centuries-old insignia and emblems".
