Your trademark tells target groups who you are. It is a way to recognise and remember a brand and to build awareness and reputation. Almost 135 000 trademarks are registered every year with the European Union Intellectual Property Office and under Estonian leadership the Three Seas logo has now become one of them.

With the trademark, a simple and memorable visual identity has been created for the initiative that will be used to draw attention to the Three Seas region and its development potential. The logo comprises a representation of the number 3 with part of the upper and lower arcs cut out and the text ‘Three Seas’.

This figure symbolises the investment needs of the countries that have joined the initiative in three main areas: the transport, energy and digital sectors. It is also symbolic of the three seas the countries border: the Adriatic, the Baltic and the Black Sea.

The logo may be used by Three Seas member states, partners and third parties to advertise activities and events that embody the same values and objectives as the Three Seas Initiative.

If you would like to use the logo, please let the Three Seas secretariat know by e-mailing
