Póvoa de Varzim is also present on the European Cultural Itinerary of the Route of Santiago de Compostela. By transcending the spiritual aspect, the cultural exchanges between the cities are permanent and renewed and happen between the creative fields of UCCN: Literature itself – as a support for documentary or fictional narratives about the Route of Santiago de Compostela - and the synergies around Music, Crafts and Gastronomy. The Route of Santiago de Compostela represents an opportunity for the cities for local development based on culture and tourism. Póvoa de Varzim hosts, for this purpose, the International Route of Santiago de Compostela (2014-2018) Conferences to discuss common opportunities and strategies.
The networks of cities allow participating municipalities to cooperate, share ideas and experiences in order to achieve common goals, especially in the field of mobility, sustainable development, education and culture. Póvoa de Varzim, with this in mind, has joined some national and international networks with other cities, with similar characteristics and objectives that bring them together.
The Rocha Peixoto Municipal Library is part of the National Network of Public Libraries (RNBP). The network was created in 1987 with the purpose of establishing a public library in all Portuguese municipalities, while also providing technical support and/or funding. There are currently 238 libraries in the network.
The fact that it is located in the Metropolitan Area of Porto (AMP) already implies its participation in initiatives and projects that contribute to the enhancement of the cultural heritage of the cities covered. Of note in this respect are some of the various initiatives in which Póvoa de Varzim is involved in the cultural and heritage field: The iPorto project consists of a metropolitan agenda of cultural events, which makes the AMP cultural calendar available online, as well as information on cultural and leisure facilities and infrastructures; the PIN portal gathers in one site the museums and points of interest of the AMP's architectural and archaeological heritage and provides information on each site. Lastly, regarding the intangible heritage component, AMP provides another portal with audiovisual records of themes related to each municipality. In the case of Póvoa de Varzim, the municipality chose to highlight the Poveira Launch, a type of traditional boat of Póvoa de Varzim.
The National Network of Sea and River Culture began in May 2002, with the aim of safeguarding and enhancing the maritime heritage, and also due to the perennial influence of the sea on Portuguese culture.
