Namdaemun, (남대문,南大門), (formally known as Sungnyemun (숭례문,崇禮門), (Metro Line 1, City Hall stn). The Great South Gate is a symbol of Seoul and has been designated as National Treasure Number 1. Particularly beautiful when floodlit at night, and best combined with a visit to the adjacent Namdaemun Market. Unfortunately, an arson lit fire in February 2008 destroyed much of the structure,and rebuilding is not expected to finish until 2012.
