The facility is built almost entirely underground to preserve the surface-level green space and historic silhouette of the Harbiye district.
It occupies a total area of 120,000 square meters across seven levels, most of which are below ground.
The complex is physically connected to the Lütfi Kırdar Convention and Exhibition Center and the Muhsin Ertuğrul Stage, forming a singular 'Congress Valley'.
The Harbiye Auditorium, housed within the ICC, features a high-tech stage capable of hosting complex large-scale theatrical productions.
The center was specifically designed to handle high-capacity international events, boasting the largest auditorium capacity in the region.
The Istanbul Congress Center (ICC) is a major multi-purpose venue situated in the heart of Istanbul's Harbiye district. Designed to host international congresses, exhibitions, and cultural events, it features a modular architecture that spans several underground floors. The facility includes the Harbiye Auditorium, which is one of the largest concert and performance halls in the city. Its construction was part of a larger urban project aimed at revitalizing the nearby congress valley, which also includes the Lütfi Kırdar Convention and Exhibition Center. The venue is fully equipped with advanced acoustic technology and multiple breakout rooms for simultaneous sessions. It frequently hosts global summits, major award ceremonies, and theater performances.

Bring a light sweater or jacket, as the building's climate control system is often set to keep large halls quite cool.
Do not attempt to enter the facility during high-security summits if you do not have pre-registered credentials or event tickets.
Business formal or smart casual attire is expected for most professional conferences held at the venue.
