Relations between design and architecture, city and landscape are strongly associated with our mission as architects against the degradation of our living sites. In recent years we are somewhat powerlessly witnessing the progressive loss of importance of the role of Architecture. Considered a tool to build high quality public spaces and places, Architecture is blurred by the widespread intention to create spectacular effects, which produce self-referral images. We must resist the progress of such distortion in an attempt to recommence from the underlying sense of the architectural project by revisiting all the specific traits of the land, its culture and history. Each time we must do our best to further define the landscape. We are accustomed to a 3D spatial idea of the world we live in. We can then consider the time. But perhaps there is also a fifth dimension of space, namely urban culture and landscape. This dimension is a matter of memory, history and stratification and, therefore, of landscape.
