A monumental abstract piece of sculpture by Giorgos Zoggolopoulos is installed at the entrance of DET (Thessaloniki International Exposition)

 Giorgos Zoggolopoulos (1903-2004) is a unique artistic personality of the 20th century in Greece. He created his most personal, innovative, and mature work from the 70s to the 90s, and he was called a "perpetual teenager" thanks to his constantly transforming artistic language and his experimentation with forms and materials. His creative beginning can be placed in the realistic style of the 30s. Still, he managed to break away from the formal barriers of his education and explore abstraction and later on mobile art, sustaining a constant dialogue with all the avant-garde movements of the second half of the 20th century. It is not by accident that he was one of the very few artists who lived and worked in Greece his whole life and, yet, he enjoyed wide international recognition.

However, in 1966, the installation of his sculpture Cor-ten, a 17,75 meters piece at the north entrance of the Thessaloniki International Exposition, provoked outrage among the inhabitants, and it was called a "monster." The sculpture, which can be considered as the pinnacle of Zoggolopoulos' geometric art expression, also initiates the sculptor's experimentation with the play between light and shadow and the use of glass lenses and water as sculptural mediums.
