Tatev  [Armenia, 2004]
Perched on the edge of a precipitous canyon in southern Armenia, parts of Tatev Monastery date back as far as the 9th century. Getting there is half the fun - a battered minibus runs only a few times a week, and takes well over an hour to cover the 25km from the town of Goris. 
Tatev's antiquity is a reminder that Armenia is the world's oldest Christian nation. It converted in 301 AD, decades before the Roman Empire.
