Built in the 1st centuries B.C. and A.D. under
Dacian rule, these fortresses show an unusual fusion of military and
religious architectural techniques and concepts from the classical world
and the late European Iron Age. The six defensive works, the nucleus of
the Dacian Kingdom, were conquered by the Romans at the beginning of
the 2nd century A.D.; their extensive and well-preserved remains stand
in spectacular natural surroundings and give a dramatic picture of a
vigorous and innovative civilization.
