The Rosa do Metro do Porto line will connect the Boavista Rotunda/Casa da Música area to Praça da Liberdade, in the centre of Porto, for about 3 km. With a completely underground route, it will have four new stations: Boavista/Casa da Música (adjacent and connecting with the current Casa da Música station), Galicia, Hospital de Santo António, and Liberdade/S. Bento (adjacent and connecting with the current S. Bento Metro station).
