Two male workers wearing work gloves and head wraps manually lift and stack red clay bricks atop a large outdoor pile at a brick kiln factory in Al-Qalyubia, Egypt. A tall smoking factory chimney rises in the background against a partly cloudy blue sky, indicating active kiln operations. Brick kilns are a common traditional industry in the Nile Delta region, producing the red clay bricks (طوب أحمر) widely used in Egyptian construction.
