Adrijo is derived from the combination of the Italian word ADRIATICO and the Croatian JADRANSKO. It describes a sea the Adriatic that unites two cultural identities as well as two shores. Here there exists a supranational Adriatic citizenship in which peoples, nations, languages, cultures, and knowledge come together and thrive.

With Adrijo, the partners of the REMEMBER project have launched a process of rediscovery and enhancement of the historical, cultural, and political ties that unite ports, cities, and territories traditions connected to the sea, to local culture, society, and economy, that are the motor for development and innovation.
