some muscular modernism of the 60's and 70s in rio: just south of the old centro and west of the commercial high rises on a road that leads towards santa teresa, a pedestrian path lifted at a higher level from the road leads across the petrobas headquarters by Roberto Luís Gandolfi. Across the bridge on the other side, is the massive and monumental cathedral metropolitano with it's conical shell with egg-crate inserts filled with stained glass.
