Both artistic and functional, weather vanes have served for many generations as visual landmarks atop roof ridges and chimneys. As part of the urban landscape, they invite an active gaze, revealing varied silhouettes against the sky. The oldest among them that have survived to this day stand as a testimony of the artisanal traditions of the past.

In the district of San Isidro, there are numerous weather vanes featuring diverse figures: coats of arms, real or fantastical animals, banners, airplanes, ships, sports, hunting scenes, domestic vignettes in the style of a sainete (short comic opera), and even unique identity-based and hagiographical themes—such as the weather vane of San Isidro Labrador alongside his plow and the angel.
