The CCCB's programme of itineraries is set in the context of Cerdà Year with propose which highlights the urbanistic richness of the Cerdà Project.

Starting in July 2009 and continuing throughout 2010, the CCCB's programme of itineraries is set in the context of Cerdà Year with propose which highlights the urbanistic richness of the Cerdà Project by analysing the present of the Eixample and envisaging the future of the city of Barcelona.

These are some of the proposal:

The underground city, The road network is the most high-profile feature of Cerdà's project, approved in 1859, but his technical and hygienist concerns led him to formulate other, less visible proposals that were to be carried out underground in the city.

Cerdà tour: green spaces on the limits of the Eixample, The periphery of Cerdà's Eixample contains a unique sequence of green spaces that offer other ways of understanding green space in the city.

The limits of the Cerdà plan, We'll be taking a deliberate look at the Eixample as a whole, from the hills of Barcelona, prime vantage points very close to the city centre, some of which are now parks and others green spaces with low-level development.

The Eixample, the shape of the city, This itinerary compares and contrasts the project for a new city formulated by Cerdà with present-day reality, showing which elements have continued which are new, the biggest changes and the way the original urban fabric has adapted to new needs.

Besòs: from boundary to public space, the river Besòs has historically had intense relations with the towns around it. Today, the Besòs is an agent of metropolitan urbanness of the first order, configuring a public space that gives a shared identity to a series of towns and paves the way for an urban continuum where there used to be just a marginal boundary.

Llobregat: a new metropolitan axis, today, in the context of metropolitan Barcelona, the river Llobregat plays a vital role in the organization of the territory. During this itinerary we explore all of these variations of a complex, constantly changing territory

New views around the old wall, this itinerary explores the territory of contact between the old and the new city, and identifies, on the spot, the principal transformations in the city since its walls were demolished.
