Hidden along the winding Arrabassada road in Collserola lie the crumbling remains of the Sant Jeroni de la Vall d’Hebron monastery, once a royal foundation that overlooked Barcelona for more than 400 years. Founded in 1393 by Queen Violant de Bar, the site was abandoned in 1835 and has since been steadily erased by modern development. A petrol station now sits atop the ruins, and litter piles up where monks once walked.
Decades of fly-tipping have transformed the site into an unsightly dumping ground. Old car tyres, broken furniture and construction debris mingle with fragments of medieval pottery. Volunteers from local associations have organised clean-up efforts, removing sacks of rubbish and highlighting the site’s historical value, but the neglect continues.
Activists warn that the heritage of the monastery is being lost under layers of waste. ‘It’s a disgrace that a site of such cultural importance is left like this,’ said members of the Associació d’Amics del Monestir de Sant Jeroni. Campaigners are pressing the city to take stronger measures to protect and restore the area.
Barcelona City Council has acknowledged the problem but says the land is privately owned, complicating efforts. Officials note that annual clean-ups and brush clearance are carried out with volunteers, but residents remain frustrated at the lack of meaningful progress. For now, the ruins remain trapped between historical significance and everyday neglect.
