Cultural Complex 1
The entrance to the Complexo Cultural da República (Cultural Complex of the Republic) by Oscar Niemeyer. Like many of Niemeyer’s cultural buildings of this period it has the stately elegance, stillness and somewhat disturbing feeling of an Ancient Egyptian tomb.

Love this one. Does it have any windows? I think I might get quite claustrophobic.
No, no windows! There are, I think, five openings in the dome, three of which are external entrances, and two of which are at either end of the flying walkway.
