The road takes you to the Pucar� of Tilcara, province of Jujuy, Argentina.
-Pucar� in ancient Quechua language means unreachable fortress-

The lower hill at the left is an strategic view point and was a populated citadell, from where the local tribe of Diaguitas (before the Spanish conquest) kept safe their little empire from other warrior clans.
