Barcelona’s Nou Barris district is set to unlock the doors to 28 of its most emblematic buildings and facilities this weekend, offering a rare chance for the public to explore a rich architectural history that often lies beyond the typical tourist trail. The ‘Open Barri‘ event, taking place on 28 February and 1 March, is the first in a series of neighbourhood-focused open house weekends, celebrating the city’s designation as the 2026 UNESCO-UIA World Capital of Architecture.

This initiative, described as a miniature version of the popular 48H Open House festival, aims to shine a spotlight on the diverse urban and architectural fabric of Barcelona’s outer districts. While the open doors event is the highlight of the weekend, it serves as the finale to a 15-day programme of talks, workshops, and debates focused on the area’s unique character. Following the launch in Nou Barris, organisers have scheduled similar ‘Open Barri’ events for La Marina from 13 to 26 April, and for Sarrià and Vallvidrera from 15 to 28 June.
From Medieval Chapels to Modernist Churches
The selection of 28 sites in Nou Barris offers a journey through the district’s layered history. Among the most anticipated openings is the iconic Castell de Torre Baró, a mock-castle perched on a hillside that has become a symbol of the district. Today, it functions as an information point for the sprawling Collserola Natural Park.
Another historical jewel is the Torre Llobeta, a heritage complex originating as an 18th-century agricultural and residential estate. The tour’s programme highlights that the tower was once surrounded by “a landscape of fields and gardens that progressively disappeared with the urbanisation of the territory.” It has since been transformed into a bustling civic centre.
Visitors can also step back in time at the Santuari de Santa Maria de Vilapicina, which has its roots in a medieval chapel, and explore historic farmhouses, or masies, like Can Verdaguer and the semi-derelict Can Valent. The tour even includes the cemetery of neighbouring Sant Andreu de Palomar, a site of significant historical importance.
A Story of Social Change and Citizen Power
The ‘Open Barri’ programme also tells the story of the district’s 20th-century development and social struggles. It includes visits to the cases barates (cheap houses) of Can Peguera, built in 1929 to house shanty town residents displaced from Montjuïc. The Canyelles housing development, built in the 1970s for a similar purpose, is also on the list.
One of the most compelling stories is that of the Ateneu Popular 9 Barris. This vibrant cultural centre and circus school occupies a former asphalt plant. Local historical accounts reveal that community pressure saved the building from demolition and led to its repurposing, culminating in a resident-led occupation in 1977.
Significant 20th-Century Landmarks
The architectural list further features prominent 20th-century public works. These include the parish church of Sant Sebastià, an austere 1966 design by celebrated Catalan architects Oriol Bohigas and Josep M. Martorell, and the district’s vital marketplaces, the Mercat de la Guineueta and Mercat de Montserrat. With some local markets like Montserrat facing challenges, as Barna.News has reported, this event highlights their importance as community hubs. The market recently reopened with a number of stalls still vacant.
Other accessible sites include the former Pi i Molist psychiatric hospital, the Roquetes Historical Archive, and the engineering marvel of the Cases de l’Aigua de Trinitat waterworks.
Plan Your Visit
The ‘Open Barri’ weekend is the main public event of a wider architectural festival that has been running since 16 February. As reported by Tot Barcelona, organisers recommend that potential visitors consult the official event schedule online before heading out. Opening times vary, and some tours may require prior reservation due to limited capacity.
This initiative provides a valuable opportunity for residents and visitors alike to gain a deeper appreciation for the architectural diversity and rich social history that defines Barcelona far beyond its famous central districts.
