Located in the La Bordeta neighbourhood, the Sant Medir Parish Church , became a landmark for the workers’ movement in the 1960s. On 20 November 1964, it played host to the first ever clandestine meeting of the Comissions Obreres Trade Union, which was attended by the workers from several factories in Barcelona.

Parish churches regularly held workers’ movement meetings during the final years of the Franco dictatorship. Clergymen such as Mossèn Josep Maria Vidal i Aunós, the Rector of Sant Medir, shared a commitment to freedom for workers and their social struggles and wage demands, thereby prompting churches in working-class neighbourhoods to work hand in hand with the new labour unions. Built as a parish in the late 1940s, with Mossèn Amadeu Oller as its first Rector, Sant Medir was identified from then on with the defence of the city’s oppressed and workers’ groups, in addition to its commitment to Catalonia. It was in Sant Medir that Abbot Escarré held his last mass before taking the road to exile; and decades later, the parish church provided a refuge for a group of 40 immigrants as an act of rebellion against the Alien Status Act issued by the Spanish government under Prime Minister Aznar. This building is now the headquarters of Sants 3 Ràdio.
