Late modern and postmodern architecture began to appear in the early 2000s. With economic development, old buildings such as Atlant House were razed to make way for new ones. Buildings with all-glass shells have appeared around the city, the most prominent examples being the International Mugham Center, Azerbaijan Tower, Heydar Aliyev Cultural Centre, Flame Towers, Baku Crystal Hall, Baku White City, SOCAR Tower and DENIZ Mall. These projects also caught the attention of international media as notable programmes such as Discovery Channel's Extreme Engineering did pieces focusing in on changes to the city.
