The Sant Leopold pavilion is located within the grounds of the Hospital de la Santa Creu i Sant Pau in Barcelona, which is considered the largest modernist enclosure in Europe. It was declared a “Cultural Asset of National Interest” (BCIN) and a World Heritage Site by UNESCO in 1997. This modernist enclosure is home to leading institutions in the fields of sustainability, health and education. The work consisted of recuperating the appearance designed by the modernist architect Lluís Domènech i Montaner. In particular this included the structural elements, building systems, original materials as well as decorative, sculptural and ornamental elements.
