the Atrium of the Basilica of Montserrat, showcasing the harmonious integration of religious and residential architecture enclosing the inner courtyard. On the left rises the elaborate, Plateresque-style stone facade of the basilica, marked by its horizontal gallery of sculpted apostles and a large circular rose window above the main entry doors. The right side is framed by a five-story building featuring warm yellow walls, decorative sgraffito details, and an open ground-floor arcade that leads out from the striking circular marble mosaic pavement below.
