The Exhibition and Research Centre of the CPHC, (Complex A) includes two subcomplexes:
1. The Research Centre, the Open-air Theatre and the Small Village.
This complex elaborates on the hybridic spatial structure of the Greek ancient theatre which arises as a natural growth and evolution of the inclined landscape of the hill, in contradistinction to the finite form of a freestanding building. It is a composition of an open-air theatre with a building block whose volume alludes to the inclined but also steep form of Greek hills, while its structure alludes to the metallic frame of a ship prow. At its top, the complex is completed with a small village accommodating workshops and exhibitions, whose form alludes to the shape of proto-urban Greek settlements. The complex includes offices, virtual-reality laboratories, library, shops, restaurant and cafe. Its inclined top is landscaped and planted and includes a number of earth and water installations of variable character. It includes the main entrance to the park as well as the start and end of the Route of Mythology, a journey via land and water, and so becomes a nodal point for the circulation inside the CPHC and a natural threshold towards the outside urban fabric.


2. The Exhibition & Media Centre, the Route of Mythology and the Cave of Mythology.
This complex is the natural continuation of complex �1�, and of the concave shape of the open-air theatre. It is entirely covered with earth, and its external form appears as a smooth, landscaped and planted hill which becomes the major green area of the CPHC. It includes the large Cave of Mythology and the main part of the Route of Mythology, two major landscape/waterscape schemes which include a number of installations and host events based on ancient Greek myths. It also includes a gorge, small caves, and oval shape passages alluding to the Greek beach-line and rocky coast, various open-air features like exhibition, play and sitting areas, as well as an open-air cinema at the top. Its interior contains large exhibition galleries for temporary exhibitions of artistic and commercial character, auditorium, a media-school with lecture rooms, bookshop, self-service restaurant and cafe. The galleries of complex ��2� form one expanded double leveled wing which penetrates into the body of complex �1�. They can operate as a whole or in subdivisions, depending on the exhibitions� requirements.

The Exhibition and Research Centre, the Art & Education Centre for Children and the Museum of the Hellenic World are the three major complexes which form the Cultural Park of the Hellenic Cosmos (CPHC).
