The 6th edition of the Three Seas Local Government Congress will take place May 27-28, 2026, in Lublin. It is a forum that brings together the visions, experience, and potential of the Central and Eastern European countries.

The Three Seas Local Government Congress is a prestigious international event organised by the Lubelskie Voivodeship. The Congress serves as a platform for cooperation among 13 countries of the Three Seas Initiative and associated members (Ukraine, Moldova, Albania, and Montenegro), focusing on infrastructure development, security, innovation, and cross-border cooperation. Over the past five editions, the Congress has gathered more than 5000 participants from over 25 countries, including representatives of governments, local and regional authorities, business, and academia. The event is held under the Honorary Patronage of the President of the Republic of Poland. Representatives of more than 350 regions from the Three Seas Initiative are invited to attend the Congress. It is a multidimensional event. Its accompanying activities include the Economic Forum, a scientific session of the Three Seas Universities Network, and the 3Seas Youth Forum. The upcoming edition of the Congress will be expanded to include a Security Forum addressed to local governments from the Three Seas region.

The Economic Forum comprehensively supports the offer of SMEs from the Lubelskie Voivodeship. Its aim is to create conditions for the development of entrepreneurship and investor services, as well as to build lasting economic relationships and facilitate the exchange of experience and inspiration in the field of the economy. Topics addressed during the Forum will include, among others: Feminine Lubelskie, Innovation, entrepreneurship (B2B Zone / Exhibition Zone), the 20th anniversary of Marka Lubelskie, and international cooperation. The Economic Forum is a unique platform for networking, signing agreements, and presenting technologies and solutions that create real opportunities for regional economic cooperation in times of global tension.

The Security Forum is a key accompanying event of the Three Seas Local Government Congress, dedicated to challenges and opportunities in the broadly understood field of security for regions involved in the Network of the Three Seas Regions project. At its core is the exchange of experience and the building of cooperation among local governments, organizations, experts, and business representatives from the 13 countries of the Three Seas Initiative. Topics discussed during the Forum will include, among others: local resilience, health and social security, protection of critical infrastructure, cybersecurity, and the role of local governments in crisis response. The co-organiser of the Security Forum is Defence24.

The 6 th edition of the Three Seas Local Government Congress will be held May 27-28, 2026, under the Honorary Patronage of the President of the Republic of Poland, Karol Nawrocki. This distinction recognises the growing importance of the event, which has become a key platform for cooperation among the countries of Central and Eastern Europe, both in the economic and infrastructural dimensions.

Over five editions of the Congress (2020–2025), more than 5,000 participants from 24 countries have taken part, 104 discussion panels have been held, and 64 foreign delegations have visited Lublin. The scale and international character of the event confirm its increasing role in shaping dialogue across the Three Seas region.

We, the countries representing Central and Eastern Europe (…) through the Three Seas Initiative, Via Baltica, and Via Carpatia, share not only our voice and vision of building a civic community, but also tangible results showing that the Baltic States and the countries of Central and Eastern Europe are capable of implementing major infrastructure projects, emphasised President Karol Nawrocki during his visit to Vilnius last month.

These words perfectly capture the spirit of the Three Seas Congress, which brings together political, academic, and business communities around a shared goal, building a strong, integrated, and cooperative Central and Eastern Europe.

It is also worth noting that in April 2025, Poland hosted the 10th Three Seas Initiative Summit. During the event, participants emphasised the importance of infrastructure and economic cooperation in the region and the need to strengthen cohesion across Central and Eastern Europe. This year, the cooperation format has been expanded to include new members – Albania and Montenegro joined the Three Seas Initiative in the capacity of associated participating states, while Spain and Turkey became new strategic partners. It has already been announced that the 11th Summit will take place in Croatia in 2026.

We cordially invite you to take part in the Three Seas Local Government Congress! Registration will open in the end of January. More details will soon be available at www.congress.lubelskie.pl and on our social media channels.
