About Rennes
Nestled in the heart of Brittany, Rennes is a vibrant city where tradition and modernity harmonize. With its medieval streets, iconic timber-framed houses, and the historic Parlement de Bretagne, Rennes tells a rich story of over 2,000 years.
As a thriving tech and research hub, home to institutions like the ECSS 2025 co-host INRIA, Rennes is a beacon of innovation and digital excellence, second only to Paris in its concentration of ICT firms.
Combine this with world-class gastronomy and proximity to the stunning Breton coastline, and Rennes becomes the perfect stage for this year's annual summit ECSS - where leaders in Informatics from across Europe come together, continue to inspire, connect, and advance the future of Informatics education and research.
