What you see on this picture is a whole industrial city made from oil platforms at the banks of Azerbaijan in the 1950s. The USSR was striving for world supremacy in industry, many decisions were made hastily. Eventually they ran out of the oil and left the place. But the metal platform will stand there for many years more till it finally collapses under the impact of the wind and salty water.
They built houses for 5000 workers, a movie-theater, parks, gyms etc. on these islands.
In 1999 some part of James Bond movie was being shot here.
In 1941 Azerbaijan supplied 175 millions of barrels of crude a year which was 75% from all the oil production in the country. That is why German troops wanted to get here during WWII so much.
