Santiago

Santiago was the capital city of Chile. Santiago Jones was born there and named for it. (TV: Death of the Doctor)

Santiago was one of ten major cities across the world, all of which had underground railways, where Coldfire Construction built a reactor within a period of 18 months as part of a plot by the Slitheen to drain the Sun's energy, operated by at least one Slitheen disguised using a skin suit made from a local. At some point in the 21st century, after Sarah Jane Smith foiled the Slitheen with the help of her friends at Park Vale Comprehensive School at Ealing in London, she contacted UNIT so they would clear up the Coldfire sites.
