Kaaba-ye Zartosht (Persian: کعبه زرتشت), also called the Kaaba or Cube of Zarathustra, is a rectangular stepped stone structure in the Naqsh-e Rustam compound beside Zangiabad village in Marvdasht county in Fars, Iran. The Naqsh-e Rustam compound also incorporates memorials of the Elamites, the Achaemenids and the Sasanians. Architecturally, it is one of several Kaabas.
The Ka'ba-ye Zartosht is 46 metres (151 ft) from the mountain, situated exactly opposite Darius II's mausoleum. It is rectangular and has only one entrance door. The material of the structure is white limestone. It is about 12 metres (39 ft) high, or 14.12 metres (46.3 ft) if including the triple stairs, and each side of its base is about 7.30 metres (24.0 ft) long. Its entrance door leads to the chamber inside via a thirty-stair stone stairway. The stone pieces are rectangular and are simply placed on top of each other, without the use of mortar; the sizes of the stones varies from 0.48 by 2.10 by 2.90 metres (1 ft 7 in by 6 ft 11 in by 9 ft 6 in) to 0.56 by 1.08 by 1.10 metres (1 ft 10 in by 3 ft 7 in by 3 ft 7 in), and they are connected to each other by dovetail joints.

Why this record matters
The phrase “stepped structure in the Naqsh-e Rustam compound in Fars, Iran” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q2363092. Authority coordinates are 29.988, 52.874. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
