Back in the early 20th century, Azerbaijan went through its first oil boom, and architects from all over Western Europe were attracted to the city to design buildings for the expanding city.

Actually, the architecture in Baku has four distinct flavors: the medieval inner city, the lavish styles from the first oil exploitation, Soviet neighborhoods and contemporary designs.
