Heydar Aliyev Center, Baku

Zaha Hadid's Heydar Aliyev Center in Baku, Azerbaijan (2012), is one of the most elegant large buildings ever constructed: a single white continuous surface that folds and flows from ground to roof, creating an auditorium, museum, and conference facility under one seamless shell. Its flowing undulations contain no sharp corners or right angles — a geometry made possible only by digital parametric design tools.
