Old Nisa, Bagyr, near Ashgabat, Turkmenistan
The Round Hall at Nisa
Mid 3rd century BC into the early centuries CE (a round hall whose job is still temple, tomb, or heroon)
Old Nisa is a 14-hectare citadel on a hill near Ashgabat, walled in mudbrick, built up from the mid 3rd century BC as a Parthian royal seat. One building is a square block with a round hall inside, 17 metres across, plastered in white gypsum. UNESCO’s evaluation says the cult purpose is clear and the specific role, temple, mausoleum, or heroon, is not.
Why this is extraordinary
West of Ashgabat, under the Kopet Dag, two mounds mark Nisa. New Nisa is the town, about 1.5 kilometres off, lived in long after the Parthians. Old Nisa is the citadel, about 14 hectares inside a rampart, the royal seat the evaluation dates from the mid 3rd century BC. Among some 2,700 ostraca, administrative scraps, one gives the name Mithradatkert, fortress of Mithradates, referring to Mithradates I, who ruled from 174 to 138 BC. A clerk’s name for a place is strong evidence of what it was called. It is weaker evidence of the year the first wall went up.
The building with the Round Hall is a square with a round room inside, 17 metres across, finished in white gypsum plaster, and a circular gallery of brick half-columns around it. UNESCO’s evaluation says you can see that this was for a cult, and that you cannot yet say whether it was a temple, a mausoleum, or a heroon, a shrine for a heroised dead. Statues of dynasts stood in it. One reading makes it the royal cult of Mithradates I, if a head is his portrait. Another reading wants a body, and the royal tombs that a Greek road-book places at Nisa have not been found. A heroon lets the king be honoured without the skeleton. All three are still on the official list because the dig has not ended the sentence.
The ivory rhytons were a different room’s treasure. They lay on a bench in the Square House, where looters had missed them. The horns keep the shape of the tusk. The ends are figures in the round, Greek and Iranian together, a winged lion-griffin among them. One inscription calls on Hestia, the Greek goddess of the hearth, which is why the vessels are read as ritual and not only as rich tableware. A frieze carries the twelve Olympian gods. That is a sky, in the sense that those gods are heaven’s household in Greek telling, carved on a Central Asian horn by more than one hand working to one programme. It is not a door aimed at a star. The horns were in storage. The Round Hall’s axis is not given an azimuth in the evaluation. Colour that once filled the carving is mostly gone.
Gonur, far out in the desert of the same country, is the Bronze Age city, a different millennium. Darvaza is a gas crater lit in the 20th century. Neither is this hall. The photograph is the excavated mudbrick of the citadel, a paved walk, the mountains behind. The white round room is one of these buildings and is not captioned in the frame. The rhytons are in a museum case. What this changes: Parthian Nisa had a round cult room whose exact job is still a three-way choice, and a set of drinking horns that put Greek gods on an Iranian royal bench. The tomb, if the hall is a tomb, has not produced a body.
Why it matters
If the hall is a temple, the Arsacid house kept a round sanctuary inside a fortress that was not mainly a fort. If it is a tomb or a heroon, the royal dead are still missing, because the tombs a Greek itinerary mentions at Nisa have not been found.
An ostracon among about 2,700 administrative texts gives the place-name Mithradatkert, the fortress of Mithradates, tied to Mithradates I in the 2nd century BC. The walls and the monumental buildings are older than that king in the evaluation’s account, a royal residence from the mid 3rd century BC. New Nisa, a larger town 1.5 kilometres off, kept living through the Middle Ages. Old Nisa’s great buildings belong to the Parthian centuries and fade as the Arsacid kingdom falls in the 3rd century CE. The Round Hall sits in a square plan, with a circular corridor of brick half-columns around the plastered room. Statues identified as dynasts were found in it. That is why a royal cult, perhaps of Mithradates I, is one reading, and why a mausoleum is another. A heroon is a shrine of a heroised dead person, which splits the difference. The ivory rhytons were not in this hall. They were stored on a bench in the Square House, a treasury building, horns carved with Greek and Iranian figures, one of them inscribed with an invocation of Hestia, the Greek hearth goddess. A frieze of the twelve Olympian gods is described on the horns. That is a sky in ivory, a Greek divine set on a Central Asian drinking vessel, not an azimuth of the Round Hall. No bearing of the hall’s axis is printed in the evaluation. Darvaza, the burning crater, is a 20th-century gas pit and is not this citadel.

Location and dating
- Location
- Old Nisa, at Bagyr, just west of Ashgabat, under the Kopet Dag. The pin is the citadel, 37.952 north, 58.210 east. New Nisa is the neighbouring town mound, 1.5 kilometres off, and is not this hall.
- Period label
- Current consensus — open to revision Monumental Parthian buildings from the mid 3rd century BC into the early centuries CE. The ostracon names Mithradatkert in connection with Mithradates I, 174–138 BC. The Arsacid kingdom ends in 224 CE. The rhytons belong to the citadel’s Parthian storerooms.
- How this dating was done
- Inscriptions on ostraca, the historical dates of the Arsacid kings, and the typology of architecture and ivory. Not a radiocarbon printed for the Round Hall in the evaluation.
- What could change it
- A body, or a foundation deposit with a king’s name, under the Round Hall would choose mausoleum over empty temple. A measured axis of the hall against the horizon is not required for that. It would matter only if the round plan were read as aimed at a star.
What is actually there
- Old Nisa is about 14 hectares inside a defensive rampart.
- The Round Hall is 17 metres across, inside a square building, plastered white.
- UNESCO says temple, mausoleum, or heroon are all still open.
- About 2,700 ostraca include the name Mithradatkert.
- The ivory rhytons were stored in the Square House. One invokes Hestia. A frieze shows the twelve Olympians.
- No azimuth of the hall is published in the evaluation.
Open questions
| Question | Status |
|---|---|
| Was the Round Hall a temple, a tomb, or a heroon? | Open. The cult use is accepted. The specific role is what the evaluation withholds. |
| Do the Olympian rhytons date a Greek sky cult at Nisa? | Open as iconography. They are a stored set of ritual vessels, not a building aligned on a star. |
The current narrative
Where publication stands today. It is the best-supported reading, and it is open to revision. It is not a verdict.
The current narrative — open to revision
A hall for the royal cult, function still open
The Round Hall served the Arsacid royal cult. Whether it was temple, mausoleum, or heroon is not settled, and the rhytons show the citadel held ritual vessels either way.
What supports this
- The evaluation calls the cult function recognisable and lists the three roles as still open.
- Statues of dynasts in the hall pull the cult toward the kings, not toward a generic store.
- Rhytons inscribed and carved with gods are ritual objects from the same citadel, even though they sat in the Square House.
What pushes back
- No body has been found to make the mausoleum more than a plan.
- The tombs Isidore mentions at Nisa are explicitly still missing. A heroon without a grave is a reading, not a discovery.
- “Cult” is the wide word. It covers all three roles, so it does not choose.
What would settle it
It is the centre because the building is obviously not domestic and the evaluation stops at the three-way split on purpose. It moves if a burial, or a dedicatory text, is found in the hall.
Emerging narratives
Other published readings. Each may be right. None is adopted here unless the evidence carries it.
An emerging narrative
A temple of the living cult, tombs elsewhere
The hall is a temple for rites of the living court. The royal tombs are another place, still unfound, and the statues are offerings or portraits, not a grave.
What supports this
- A round plastered room with a processional corridor fits a temple plan as well as a tomb.
- The known tombs have not turned up inside this building, after decades of excavation.
- The rhytons’ home is the Square House, a treasury, which is a place for gear used in ceremonies and then put away.
What pushes back
- Statues of dynasts inside the round room are an odd congregation for a temple that is not about those dynasts.
- A heroon was invented as a category exactly because temple and tomb both fit and neither is proved.
- Missing tombs prove the tombs are missing. They do not prove this hall was never one.
What would settle it
It stays because the absence of a body is real. It is not the centre while the evaluation refuses to drop mausoleum and heroon from the list.
Should the current view be reevaluated?
Open to revision
Old Nisa is a firm Parthian royal citadel. The Round Hall’s cult use is firm. The choice among temple, tomb, and heroon is the sentence UNESCO leaves unfinished, and no star bearing is printed to complicate it further. Open is that unfinished sentence.
What drives this
- A 17-metre round hall in a square building, with dynastic statues.
- Three roles still listed in the World Heritage evaluation.
- Rhytons with an invocation of Hestia and a frieze of the twelve Olympians, stored in a different building.

If the contested reading is right
What would follow if a reading that is not the consensus turned out to be true, and what could settle it. This explains the stakes. It does not adopt the reading.
The Round Hall is the royal mausoleum or heroon
The Arsacid ancestor cult would have a building, and the still-missing tombs named in the Greek itinerary would be either this hall or a deliberate second grave somewhere else on the hill.
Why it is still worth a test
A burial, or an inscription that names the hall’s dedicatee, under or in the round room.
