Editing Sarmizegetusa Regia (section)

=== Roman era ===
Sarmizegetusa's walls were partly dismantled at the end of the First Dacian War in AD 102, when Dacia was invaded by the Emperor [[Trajan]] of the [[Roman Empire]] and rebuilt as Roman fortifications. The latter were subsequently destroyed, possibly by the Dacians, and then rebuilt again following the successful siege of the site in AD 105–6.<ref>{{Cite journal|last1=Oltean|first1=I.
