Barcelona will dedicate 2026 to celebrating the life and legacy of the man who engineered its modern identity, Ildefons Cerdà, with a year-long programme of events marking the 150th anniversary of his death. The ‘Year of Cerdà’ will honour the visionary urban planner whose groundbreaking design for the Eixample district transformed Barcelona and set a global standard for city planning.

Ildefons Cerdà, an engineer and urbanist who died on 21 August 1876, is celebrated for his scientific and humanistic approach to city design. In the mid-19th century, as Barcelona’s medieval walls came down, Cerdà conceived of a vast grid-based expansion, the Eixample (or ‘Expansion’). His plan was revolutionary, prioritising sunlight, ventilation, green spaces, and efficient transport to improve public health and social equity. Its distinctive chamfered corners, or xanfrans, were designed to ease traffic flow and create small public squares at every intersection, a feature that remains an iconic part of the city’s landscape.

A City-Wide Commemoration

The year-long tribute, officially launched this week, will encompass academic, cultural, and community activities across the city and beyond. According to reports in El Nacional, the commemoration will extend from Barcelona to Madrid, where an institutional homage is planned at the Spanish Congress of Deputies, and to Cerdà’s birthplace, the town of Centelles.

Key events in the programme include:

  • Exhibitions: The Col·legi d’Arquitectes de Catalunya (COAC) will host a major exhibition from July 2026, analysing ten leading contemporary cities through the lens of Cerdà’s principles. A separate travelling exhibition will visit Centelles, Barcelona, and Madrid.
  • Academic Forums: The first annual Symposium on Ildefons Cerdà will take place in Centelles, while Barcelona’s Centre de Cultura Contemporània (CCCB) will host the Cerdà Seminar in November 2026.
  • Professional Conferences: The Col·legi d’Enginyers de Camins (College of Civil Engineers) will lead a series of discussions on modern urban challenges such as mobility, housing, and public health, all central themes in Cerdà’s original work.
  • Public Engagement: To bring Cerdà’s story to a wider audience, the programme includes a 12-episode podcast exploring his ideas and their modern relevance, alongside cultural and family-oriented activities.

A Legacy ‘More Present Than Ever’

During the launch presentation, political figures stressed the enduring importance of Cerdà’s work. Sílvia Paneque, the Catalan Minister of Territory, described Cerdà as a “visionary” who imagined a city designed to improve the lives of its inhabitants. “He was able to imagine a city designed to improve people’s lives, with criteria that today continue to be central to the urban debate,” she remarked, as documented by the Catalan government.

Laia Bonet, Barcelona’s First Deputy Mayor, echoed this sentiment, stating that Cerdà’s legacy is “more present than ever.” She added, “To speak of Barcelona is to speak of Cerdà,” noting that his focus on “housing and mobility as the two great facts of urbanisation” remains entirely relevant today. These debates continue to shape the city, from high-profile projects exploring Barcelona’s unique urban formula to contentious legal battles over local development plans in districts like Gràcia.

Josep Paré, the mayor of Centelles, also highlighted the planner’s origins. “While everyone associates Cerdà with the Eixample of Barcelona, we must also remember that he is a son of Centelles and that the landscape where he grew up influenced his thinking,” he said, reclaiming the local roots of a globally influential figure.

Cerdà’s Enduring Influence

The ‘Year of Cerdà’ aims not only to look back but also to use his principles as a framework for addressing future challenges. His radical ideas on creating a healthier, more equitable city prefigured many contemporary movements in urban planning, including the 15-minute city and Barcelona’s own ‘superblock’ (superilla) transformations.

As the city prepares for this extensive commemoration, the streets of the Eixample stand as a living testament to Cerdà’s foresight. It is a district that seamlessly blends grand boulevards with intimate neighbourhood life, home to architectural marvels and beloved local institutions alike. The celebration in 2026 will offer residents and visitors a chance to rediscover the visionary who laid the foundations for the Barcelona of today.
