摘要：This paper examines how cross-border regions can generate, under certain preconditions and with EU support, territorial cooperation based on local endogenous development, reducing the effect of mental and physical borders as a potential new centrality. The tools made available by the Communitarian legislature (as European Grouping of Territorial Cooperation or INTERREG programme) therefore should not be perceived as an aim but rather as a means to support this process.The research is divided into three parts. The first reviews the evolution of cross-border cooperation in Europe. The second part analyzes the Pyrennees as a region involved in the last INTERREG IV-A (POCTEFA) programme, focusing on some elements supporting the practice. The last section analyzes the case of the Cerdanya valley, underscoring the homogeneity of the territory, the historical and current cooperation, the limits and some advice to improve it.
