If you have seen more than one photograph of Rio, chances are it was of the mountain that overlooks the city with the statute of Christ. Sitting atop Mount Corcovado, is the statute that was designed by Paul Landowski and built by Brazilian engineer Heitor da Silva Costa. The construction took 9 years, from 1922 to 1931. It is made of reinforced concrete and soapstone. One more fun fact - it is listed as one of "New 7 Wonders of the World".
And the surrounding mountains.
Oh, and we probably could have avoided the obnoxious tourists taking selfies making it very difficult to photograph the Christ without having them in the picture.
