Everything is blue here. The walls, the buildings, the alleyways, the pavements, and the steps, all in blue. Yes, there is a beautiful city in Morocco, which is known for its colour. The Chefchaouen or Chaouen is known as the Blue city. It is known as the blue pearl of Morocco as well because of this obvious reason. Chefchaouen, a small historical city in Morocco, is a famous tourist destination. This city is also known for its beautiful surroundings and architecture. But what makes it truly different is the ample use of the colour blue. Wherever one looks it’s blue and only blue they will see. The city is situated in the picturesque Rif mountains. If one needs to dig the reasons behind its blue colour it's important to understand some history connected with the city. This city was founded in 1471 by Moulay Ali ibn Rashid al-Alami. In 1920 the Spaniards captured Chefchaouen. Then it became part of Spain's territory in Morocco. During the 1930s, the city witnessed the arrival of Jews. The majority were fleeing during the Second World War.

In 1956 the city was gained back by Morocco when the country got independence. Then why is the city blue? According to historians and the people here, the reasons are aplenty. According to some, painting the walls blue would have likely happened in the 15th century,shortly after the city was founded and it is being followed from then on. Some believe that as per Islamic culture blue is said to be a colour of happiness and optimism. Another belief is that the Jewish immigrants who opted to stay in the city during the 1930s are the reason. According
to Jewish beliefs, the color blue is representative of the sky and the Jewish communities have this practice of painting things in blue as per their religious belief. So once the Jews started this custom, others followed suit.
Another reason is somewhat strange. Some of the residents believe that the blue colour helps to keep mosquitoes away. And the reason quoted with this belief is that for mosquitoes the blue walls look almost like flowing water and this keeps them away.

Another reason is the heat and humidity. Some believe that during warmer months the shade of blue keeps the homes cooler. Further, a few believe that through the colour blue people were trying to replicate the color of the Mediterranean Sea According to some people, from the 1970s it became mandatory to paint the walls in blue to
attract tourists as blue looks striking. Also, it has a soothing and calming effect. Maybe that is the real reason behind this blue city!
