There are quite a few displays of abandonment in Atacama, from trains, to train stations to old cars and houses.
Interestingly, it appears that there is no land ownership as such and the dwellings are made from hand built mud bricks fashioned out of straw and mud in molds. The dried bricks are then brought together in simple square rooms. A roof is fashioned out of local wood and that then becomes home.
Rather than refurbish, it appears that moving on to a new location and building a new mud brick home is easier. Therefore there ends up being a lot of abandonment in the desert.
