In 1996, at the International Union of Architects Congress held in Barcelona, Spain, the organization established that World Architecture Day should coincide with UN-Habitat’s World Habitat Day. Therefore, World Architecture Day is celebrated on the first Monday of every October, to celebrate the architect’s commitment to our societies, our ecosystems, and our cities.
