Cities Connection Project (CCP) was born with the aim to establish a network of cultural connections between Barcelona and other European cities with an important architectural tradition.One of the main elements of the "Barcelona Model" is the quality of public space, and this reason has promoted Open Space Connection (OSC), a branch of CCP, but focused in the field of public spaces in metropolitan areas. Through the first edition of Open Space Connection, the curators aim to open the reflection about two different methodologies of thinking public spaces and landscape architecture: one of them in the the French Swiss Region of Lake Leman and the other one in the Barcelona Metropolitan Area. With Augmented Reality contents in each project.
