The number of squatted social centres in Barcelona grew from under thirty in the 1990s to around sixty in 2014, as recorded by "Info Usurpa" (a weekly activist agenda). The influential Kasa de la Muntanya was occupied in 1989. In 2014, the ultimately unsuccessful attempts to evict the long-running social centre of Can Vies provoked major riots. Another long-running squat is Can Masdeu, which survived a concerted eviction attempt in 2002. Eleven occupiers suspended themselves off the walls of the building for several days.
