From October 16 to 18, 2025, Zagreb will become the heart of global innovation as the National and University Library hosts the 23rd International Innovation Exhibition ARCA. This annual event is not just for inventors and experts. It is a meeting place for dreamers, creators, and anyone curious about how the future is being built.

Over three exciting days, the exhibition will bring together inventive individuals, research teams, academic leaders, scientific institutions, and companies that are pushing the limits of possibility. With participants arriving from 30 countries, ARCA 2025 is set to showcase groundbreaking ideas that range from life-changing medical solutions to clever design concepts that brighten our daily lives.

More Than an Exhibition

ARCA 2025 is designed as an experience that blends learning with inspiration. Beyond the dazzling displays of new inventions, visitors will enjoy the International Innovation Forum, a space for professional lectures, dynamic discussions, and hands-on workshops.

Among the highlights are talks on the importance of intellectual property, organized by the State Intellectual Property Office, as well as practical sessions on grants, guarantees, and loans for entrepreneurs, led by HAMAG-BICRO. These conversations will give both newcomers and seasoned professionals a deeper understanding of how ideas can grow into successful ventures.

Younger guests are also warmly welcomed. Special STEM workshops have been prepared to introduce children and teenagers to the wonders of science and technology in a fun and engaging way. These sessions are designed to spark curiosity, build confidence, and perhaps even inspire the next generation of innovators.

Croatia on the World Map

This year carries special significance for Croatia as it takes on the role of host for the Electoral Assembly of the International Federation of Inventors’ Associations (IFIA). Representatives from leading innovation organizations around the globe will gather in Zagreb, confirming Croatia’s place as a country that nurtures research and development.

For the city and its people, this is a moment of pride. It shows how even smaller nations can play a big role in shaping global conversations about creativity and progress.

Recognizing the Best

At the heart of ARCA is the celebration of excellence. The most impressive innovations will be honored with medals and awards, including recognition from the World Intellectual Property Organization (WIPO). The highest honor, the GRAND PRIX ARCA, is reserved for the standout creation that truly captures the spirit of the exhibition.

These awards are more than trophies. They represent passion, persistence, and the courage to dream. For visitors, they are a reminder that every groundbreaking idea starts with someone daring to imagine a different future.
