Barcelona’s ambitious strategy to curb excessive noise in its historic Ciutat Vella district faces significant delays due to an ongoing legal battle, forcing the city council to redraft its plans to withstand judicial scrutiny. This setback contrasts sharply with positive developments elsewhere. A new university study confirms that the city’s green urban axes successfully reduce ambient sound levels, showcasing proven infrastructural solutions.

The core of the issue lies in Ciutat Vella, a district that is a magnet for tourism and nightlife, and consequently, accounts for roughly 20% of all noise complaints lodged in the city. City officials revoked an initial protocol in November 2023 due to procedural flaws, after it enforced earlier closing times for bars, terraces, and shops in specific hotspots for less than a year. The administration of Mayor Jaume Collboni then devised a more nuanced alternative: six specific noise-mitigation plans for the district’s busiest areas. However, the city has implemented none of these. The primary obstacle remains a legal dispute between the Barcelona City Council and the city’s powerful restaurant guild, the Gremi de Restauració de Barcelona, over nighttime noise limits.
Legal Battle Halts Progress
The legal conflict has effectively frozen the city’s strategy, especially the plan for the bustling Passeig del Born. This area was to be the first to implement a Special Acoustic Regime Zone (ZARE), a designation triggering stricter noise controls. Notably, the dispute intensified after a court order mandated earlier closing times for terraces on Carrer d’Enric Granados in the Eixample district.
Last year, the restaurant guild secured two favourable rulings. In a key decision, the High Court of Justice of Catalonia (TSJC) annulled 2022 modifications to the city’s environmental ordinance. These changes had introduced new acoustic zones and lowered permissible sound thresholds. According to a report in El Periódico, this ruling directly impacted the legal basis for the Passeig del Born ZARE.
While the city council has appealed this decision to the Supreme Court of Spain, a ruling is pending. In the meantime, the council is taking pre-emptive action. To guarantee legal security, it initiated a new approval process for the Born ZARE. This process incorporates updated sound measurements and minor boundary adjustments, aiming to fortify the plan against future legal challenges, regardless of the Supreme Court’s verdict.
Consequently, this restart means significant delays. The council now hopes to implement regulations for Passeig del Born and a similar plan for Plaça Reial “before the summer of 2026,” almost two years behind schedule. Moreover, the Gremi de Restauració has already submitted formal objections to the revised plan on behalf of 13 local businesses, questioning its legality and effectiveness.
Green Axes Proven to Quieten Streets
While the administrative battle over nightlife noise continues, a different approach to urban sound control is yielding positive results. A recent study by the Universitat Autònoma de Barcelona (UAB) demonstrates that creating green axes directly and measurably impacts noise pollution.
Published in the scientific journal Cities & Health, the research analysed data from seven permanent acoustic monitoring stations in the Eixample district, where several streets have been transformed. By comparing noise levels in 2022 (before works began) with those in 2023 (after green axes were established), the study found an average noise reduction of 3.1 decibels. This highlights the effectiveness of restricting motorised traffic and increasing green space as a noise mitigation tool, particularly for dense urban areas like the Eixample neighbourhood.
These findings offer a proven path forward for tackling traffic-related noise, complementing other technological solutions such as noise-reducing pavement being installed in nearby Granollers. However, Barcelona now faces a dual reality: while forward-thinking urban design successfully quiets some neighbourhoods, efforts to manage noise from the vibrant but loud hospitality sector in its historic heart – a core part of the wider plan for Ciutat Vella – remain tied up in legal and administrative knots.
