DON'T MIX THEM UP
Sarmizegetusa Regia vs Ulpia Traiana Sarmizegetusa
Two Romanian sites share the name Sarmizegetusa but tell opposite stories — one the Dacian capital Rome destroyed, the other the Roman city built to replace it.

It's an easy mix-up: Sarmizegetusa Regia was the sacred Dacian capital, conquered and largely dismantled by Rome in 106 AD, while Ulpia Traiana Sarmizegetusa is a separate Roman city built shortly afterward and deliberately named after the very capital Trajan had just destroyed. The naming wasn't an accident or coincidence — founding a new Roman city under the old capital's name was a pointed political statement of conquest, transferring the prestige and recognition of "Sarmizegetusa" onto a brand-new Roman foundation built to project Roman authority over the newly annexed province.
The Dacian capital: Sarmizegetusa Regia
Sarmizegetusa Regia is the remote, mountaintop site most visitors mean when they picture Dacian ruins: a terraced fortress built in the murus dacicus style, a sacred zone of rectangular sanctuaries, the enigmatic circular sanctuary, and the carved Andesite Sun set into the paving nearby. It served as the Dacian kingdom's sacred and political centre under kings Burebista and Decebalus, and has been protected as a UNESCO World Heritage Site, as part of the six linked Orăștie Mountains fortresses, since 1999 — recognised for its unique defensive and religious architecture found nowhere else.
The Roman capital: Ulpia Traiana Sarmizegetusa
Ulpia Traiana Sarmizegetusa sits roughly 40 kilometres away in lower, flatter terrain, founded in 106 AD as a colonia deducta and made the capital of the newly created Roman province of Dacia. Unlike the Dacian mountain sanctuary it was named for, this is a planned Roman provincial city, with the archaeological remains you'd expect of one — a forum, an amphitheatre, and a laid-out street grid — reflecting Roman civic administration and urban life rather than the religious, mountain-top character of the site it succeeded and was deliberately named after.
Why the mix-up happened
Part of the confusion is historical rather than purely modern: Ulpia Traiana Sarmizegetusa was excavated and documented earlier, in the early 20th century, and for a period scholars assumed it was itself the site of the old Dacian capital, since the name matched exactly and its Roman remains were considerably easier to identify at the time than the overgrown mountain terraces. It took further excavation work, eventually confirming the mountain site in the Orăștie range as the genuine seat of Dacian power, to properly separate the two sites in the archaeological record for good.
What each site is actually like to visit
On the ground, the two visits feel nothing alike. Sarmizegetusa Regia sits close to 1,200 metres up in the Orăștie Mountains, remote enough that reaching it is a genuine day trip in its own right, ending in a walk among the terraced sanctuaries and the Andesite Sun with sweeping mountain views on every side. Ulpia Traiana Sarmizegetusa, by contrast, sits on flat, easily reached ground roughly 40 kilometres away, right next to the modern village that carries the name today, with a forum, an amphitheatre, and gridded streets that give it the feel of a provincial Roman town rather than a mountaintop sanctuary.

Which one should you visit
If you're drawn to the Dacian story — kings, sacred sanctuaries, and the fortress Rome had to besiege twice before it finally fell — Sarmizegetusa Regia is the site that matters, and it's the one nearly all bookable day trips from Sibiu or the wider Transylvania region are actually built around. Ulpia Traiana Sarmizegetusa appeals more to visitors specifically interested in Roman provincial urban life. Given how remote both sites are, double-check carefully which one any tour, map pin, or search result is actually referring to before you commit your day to a plan.
