"Just wait til' you see it Katara! The Air Temple is one of the greatest wonders of the world!"
About this creation
The Southern Air Temple was exclusively for male airbenders, and was Aang's home. It was here that the young Avatar ran away from his mentor Monk Gyasto, was frozen in an iceberg while at sea, and left the airbenders to die.
This temple had always seemed like a graveyard to me, with the exception of Aang's flashbacks.
Here's a view of the flip side.
