Exhibition halls & floor plan

HEYSUN 2026 is listed by SiciliaFiera in Block C, using Pavilions C1, C2 and C3. The wider exhibition centre has six pavilions, conference rooms, press facilities and extensive outdoor areas.

The venue’s layout separates exhibition spaces, visitor entrances, parking areas, internal roads and service access. Visitors should check the latest HEYSUN floor plan before arrival because individual exhibitor locations and hall arrangements may change.

Sustainability & environmental initiatives

Sustainability is central to both HEYSUN’s subject matter and the operations of its host venue. SiciliaFiera states that it uses energy-saving lighting throughout exhibition spaces and conference areas, separates and recovers waste where possible, and promotes lower-emission transport options.

The venue also reports electricity production from its photovoltaic installations and provides electric transfer services during events. HEYSUN itself promotes renewable energy, sustainable mobility, renewable communities, energy efficiency and other technologies supporting the transition to lower-impact energy systems.

Event rules

Visitors must follow the admission, safety and venue regulations established by HEYSUN and SiciliaFiera. Exhibitors and contractors are subject to technical rules covering stand construction, electrical systems, loading and unloading, equipment operation and safety requirements.

Visitors should use the designated entrances and follow staff instructions inside the exhibition centre. Special equipment, demonstrations or operating machinery may require prior authorisation under the venue’s technical regulations.

How to get there
