No matter where you are in the city, public art seems to be very hard to find. It is only when the artwork is so ugly that the public realizes the existence of public art, and this "monstrous" way of discovery has become a channel for many people to get in touch with art. Although the ability to recognize and appreciate ugliness and beauty is controversial, much of the public **** art around the world is unacceptable, and even makes people doubt their own aesthetics.
