The European Week of Regions and Cities is the biggest annual Brussels-based event dedicated to cohesion policy. It is co-organised by DG REGIO and the European Committee of the Regions. As the name indicates, the event lasts over one week, Monday to Thursday (2020 was an exception due to the digital format). Originally conceived as an onsite event, has proven to be efficient as an onsite event as a digital format. It has grown to become a unique communication and networking platform, bringing together regions and cities from all over Europe, including politicians, administrators, experts and academics. Over the last 18 years, it has done much to promote policy learning and the exchange of good practice, confirming the event as a relevant platform for discussing and showcasing the development of EU cohesion policy, and raising awareness amongst decision-makers on the views of regions and cities and their practical proposals for EU policy-making. In 2020, the first ever digital #EURegionsWeek reached a record number of more than 12.000 participants and 510 sessions.
