This week Chile re-opened it's Arturo Prat Base in Antarctica, which was closed back in 2004. The base was opened for the first time in the 1940s. One of the reasons behind reopening it is to assert their presence and back up the rights they claim to the continent in lieu of the recent claims of seabed by countries, such as the United Kingdom. Now they are actually using this in compliance with the regulations in Antarctica and it is a scientific base just like other countries. To be added to the base is a multipurpose science lab and a museum focusing on Chile's past involvement in Antarctica.
Here is an article about the base re-opening.
