A rectangular concrete chapel in Asa Sul that hides one of the most striking interiors in Brazil. The walls are made of two-metre tall stained glass panels in twelve shades of blue, by Cláudio Naddeo, that flood the nave with a deep underwater light. A 7-metre wooden crucifix by Gotthard Schmid hangs over the altar; the floor is dark wood.
The chapel is dedicated to Don Bosco, the Italian saint who in 1883 dreamed of a great civilisation arising in the South American interior — which Brasília's founders interpreted as a prophecy of their city. Free; arrive in late afternoon for the best light.
