The Transfăgărășan is one of the most famous roads in the world. Romanians that are interested in criticizing the inefficiency of the current government, or even proud (crazy?) enough to highlight the achievements of former communist dictator Ceaușescu always bring up this road.
This very twisty road was built in the 70's as a strategic military road to allow crossing of the Carpathian mountains in case of invasion by Soviet forces. It is quite impressive.
