About

The Metropolis GZM in southern Poland is one of Central Europe’s largest metropolitan unions, bringing together multiple cities in the Silesian region. Historically shaped by heavy industry, GZM is transforming into a diversified economy focused on services, innovation, and sustainable mobility. It coordinates metropolitan transport, spatial planning, and economic development, strengthening regional cohesion and competitiveness.

Additional Information

GZM is Poland’s largest metropolis (2.3 million inhabitants, 41 municipalities), comprising Katowice as the core city alongside surrounding Silesian towns. It represents Central Europe’s most significant post-industrial urban transformation project, transitioning from coal and steel towards a knowledge economy, cultural tourism, and green technology. GZM was the first Polish metropolitan association created under dedicated legislation (2017) and operates as a strategic authority for transport, environmental policy, and smart city development.
