ENPP has one more member: the Municipality of Alcañices (Spain) decided unanimously in the Town Hall Plenary to join the Network last June 30, thus increasing to 10 the number of European countries that integrate it.

In Alcañices was signed on September 12, 1297 an important Treaty of Peace between Portugal and Castile/Spain which put an end to the border disputes between the two countries and stabilized the border that is usually considered the oldest one in Europe.
