The leaning buildings of Santos (9 pictures) by memolition · The city of Santos in Brazil has a very special problem. Under the 7 meters of sand on which a lot of the buildings were built in the 40′s, 50′s and 60′s, there is a 30-meter layer of very slippery clay. The buildings do not cope well with it.
