Copenhagen is filled with construction works for the past years, mainly due to new metro stations coming up. The working areas are usually surrounded by tall green walls but this doesn’t mean that they necessarily have to be ugly. These walls are used for exhibition of art, meaning that they are either painted very often or are decorated artistically. For me it was a great idea to brighten up all the ugliness that these works have done to this beautiful city! What do you think? Here is just the central one in Kongens Nytorv which is called the happy wall! It consists of moving parts with different colours on each side, so you can form your own words or picture on the wall!
