The city that takes good care of its cultural heritage is the city that listens to its past without neglecting its future. This delicate balance between memory & contemporaneity is what a perdurable architecture, committed to contribute to the society, provides. Those are the cornerstones for the Matta Sur Complex. Matta Sur consists of two buildings located within the same plot: the former Metropolitan Lyceum of Santiago, built in 1891, & restored to host social uses such as a nursery school, a gym or an auditorium; & a new-build construction which will accommodate a Health Center (CESFAM).
