Castell de Torre Baró, built at the start of the 20th century atop the Collserola range between Roquetes and Torre Baró neighborhoods in Barcelona's Nou Barris district, was designed as part of an unfinished hotel and urban development project. Despite its medieval appearance, this castle offers privileged panoramic views of Barcelona and its surroundings from an exceptional mirador position. Restored in 1989 and declared a historical heritage site, it now serves as an environmental education point within Parc de Collserola, providing guided tours, discovery itineraries, and educational workshops for all ages.
