La Mina Grott: Water legacy, route of the first electric train.
On Camí del Cama-sec 22 in Vallvidrera, La Mina Grott is a testament to engineering and transport. Erected in 1855, this nearly 1.5-kilometer tunnel initially channeled water from the Vallvidrera reservoir to Sarrià. By 1908, its role evolved, housing Spain's first electric passenger train – a pioneering link to the Collserola landscapes. Active until 1916, this service set a precedent for urban mobility. Today, La Mina Grott's discreet access in Sarrià-Sant Gervasi continues its hydraulic work, an enduring symbol of innovation and heritage.
