The white structure of the Institute of Ocular Microsurgery designed by Josep Llinás is nestled against Mount Tibidabo above the city, shielded from the road by green space. The southern façade is broad and inviting, allowing the offices and cafeteria to benefit from daylight and a view of the city, while protruding roof areas and the arrangement of openings and skylights contribute to a subdued interior light level that is appropriate for patients undergoing eye surgery.
