The Heydar Aliyev Cultural Centre in Baku, Azerbaijan was designed by Zaha Hadid Architects. It features a continuously curved roof that forms the ceilings, walls, and stairs of the building. The complex houses a concert hall, museum, and library under one seamless roof made of 970,000 square feet of curved steel segments. The building had to withstand Baku's harsh environment of high winds, earthquakes, and pollution. Its unique design and advanced structural system allow it to blend with the landscape while remaining durable in the extreme conditions.
