World Architecture Day is celebrated on the first Monday of October each year. It was established by the International Union of Architects (UIA) in 1985 to promote the importance of architecture and its impact on society. The day encourages architects, designers, and the public to engage in discussions about the built environment and sustainable development. Each year, World Architecture Day has a specific theme that highlights current issues in architecture and urban planning. Events, exhibitions, and lectures are organized globally to raise awareness about the role of architecture in improving living conditions and fostering cultural identity.
