The EPA is developing other methods to promote cross-border cultural tourism. The Council of Europe`s expanded sub-agreement on cultural routes (EPA), concluded in 2010, aims to strengthen the potential of cultural routes for cultural co-operation, sustainable territorial development and social cohesion, with particular emphasis on symbolic issues for European unity, history, culture and values and the discovery of lesser-known destinations. In December 2010, the Committee of Ministers of the Council of Europe adopted Resolution CM/Res(2010)53, which established, for an initial period of three years, an enlarged partial agreement on cultural routes (EPAs), confirmed in 2013 by Resolution CM/Res66, in order to allow closer co-operation between States particularly interested in the development of cultural routes. The expanded sub-agreement on cultural routes aims to strengthen the potential of cultural routes for cultural cooperation, sustainable territorial development and social cohesion, focusing on symbolic themes for European unity, history, culture and values, as well as on the discovery of lesser-known objectives. “Routes4U” (2017-2020) is a joint programme of the Council of Europe (DG Democracy) and the European Union (EC, DG Regional and Urban Policy). The programme aims to contribute to the sustainable and imaginative development of the EU`s four macro-regions through the Council of Europe`s Cultural Routes, by developing the culture and tourism industry in the region and by strengthening the participation of civil society and local actors. The Routes4U project is the first of its kind and creates synergies between two transnational programmes of two international organisations, namely the Cultural Routes of the Council of Europe programme and the EU`s macro-regional strategies, including EUSAIR (EU Strategy for the Adriatic Ionian Region). Eusair has implemented specific actions to promote and disseminate cultural routes of Greek interest, namely the Olive Tree Route and the Roman Imperial Road (under development). In December 2010, the Committee of Ministers of the Council of Europe adopted a resolution on the creation of the Extended Agreement on Cultural Routes (EPA). This agreement was intended to facilitate the financing and organization of the program.
The EPO has its headquarters at the EICR and regularly brings together representatives of certain states more interested in the programme, empowered to certify new cultural routes and to evaluate routes already certified.  The European Institute of Cultural Routes (EICR) was created in 1998 following a political agreement between the Council of Europe and the Luxembourg government. . . .
