In mid-April, vacationers on the beach in Barcelona noticed something unusual in the sea. The outlines of high-rise buildings appeared directly on the horizon, while they also floated in the air.
Photographer Javi Kabo, who witnessed this strange sight, took a picture of the “ghost town” and published it on social networks.
In fact, of course, there were no skyscrapers in the sea. Instead, eyewitnesses at the beach could observe an optical illusion known as Fata Morgana.
It occurs when layers of air have different temperatures and densities, due to which light refracts and objects visible in the distance are distorted. As the photographer explained, the “skyscrapers” in Barcelona were actually just a container ship, writes La Vanguardia.
