Baku, the capital and commercial hub of Azerbaijan, is a low-lying city with coastline along the Caspian Sea. It’s famed for its medieval walled old city, which contains the Palace of the Shirvanshahs, a vast royal complex, and the iconic stone Maiden Tower. Contemporary landmarks include the Zaha Hadid–designed Heydar Aliyev Center, and the Flame Towers, 3 pointed skyscrapers covered with LED screens.
Baku Heydar Aliyev International Airport is one of the six international airports serving Azerbaijan. Formerly, it was called Bina International Airport by the name of a suburb in Baku.
