Trinitat Vella is a station in the Barcelona metro network, currently served by the TMB-operated L1. It's named after the neighbourhood Trinitat Vella, in the Sant Andreu district of Barcelona, and the park of the same name. It is quite unusual in being one of the few stations with an attached building overground, which lies on the Nus de la Trinitat and links the neighbourhood with Parc de la Trinitat.
