Sarmizegetusa Regia
Sarmizegetusa Regia (also known as Sarmisegetusa, Sarmisegethusa, Sarmisegethuza; Ancient Greek: Ζαρμιζεγεθούσα, romanized: Zarmizegethoúsa) was the capital and the most important military, religious and political centre of the Dacians before the wars with the Roman Empire. Built on top of a 1200 m high mountain, the fortress, consisting of six citadels, was the core of a strategic and defensive system in the Orăștie Mountains (in present-day Romania).
