This is a detail from the Dragon Fountain found on the City Hall Square in Copenhagen. The big orange balloon in the background contains CO2 and was a way to raise peoples awareness on
The Dragon Fountain was inaugurated in it's original form in 1904 without the bull in the middle. The artists were Thorvald Bindesbøll and Joakim Skovgaard. They lost a competition held by the Association for the Beautifying of the Capital in 1889 for a fountain on Højbro Plads but it was later decided to use their design near the City Hall instead. It was ridiculed and compared to a spittoon for many years until the bull was added in 1923. Now it is a favorite hangout for the many pigeons at the square and they don't just spit on it!
