Eight Antarctic buildings that have the X Factor

Following the unveiling of the Discovery Building today, we look at eight architectural highlights from Antarctica over the past 20 years.

By far the world's least developed continent, Antarctica has very few buildings.

Two simple huts built in 1899 were the first structures to be constructed on the continent, but as exploration has continued, research bases have grown in complexity and scale with the Discovery Building designed by Hugh Broughton Architects being the latest addition.
