The main guiding concept of the City Park project is that of a Perimeter Park with an intensive use border that surrounds and protects a pre-existing natural reserve of the biosphere in its interior, enhancing and recovering the historical legacy of the buildings of patrimonial value that is housed inside. The layout of a perimeter park on the edge resolves an optimal spatial transition between the space of the consolidated city and the space proposed as a nature reserve.

​

It is consolidated as a pedestrian ring of intensive use without time restrictions, composed of a system of green spaces and sports activities complemented by service spaces and places of small commercial concessions, guaranteeing a necessary urban vitality of activities throughout its perimeter at multiple times.
