In Arter, My favourite work of art is Black Diamond which belongs to Ahmet Öğüt. This work have good place for exhibition. A diamond has taken from wall of Arter. Art lovers can search a ‘’Black Diamond’’ in 9 tons coal mine. If you find ‘’Black Diamond’’, you win it. Also this situation provide people amazing experience. On the other hand, artist provide people question this work on their mind. For me, as a person who born in Zonguldak, attending this work cause great memory. Also, this work is presented in Van Abbemuseum in Holland.
