Source-derived summary

The Castle of Oblivion (Old Armenian: բերդ Անուշ berd Anush), also known as the Prison of Oblivion or the Fortress of Oblivion, was a castle and political prison of the Sasanian Empire located in Khuzestan in southwestern Iran. According to the Buzandaran Patmutʻiwnkʻ and Procopius' Persian War, the name referred to the fact that it was forbidden to mention the name of the castle or its prisoners. It may be identifiable with the fortress of Agabana mentioned by Ammianus Marcellinus as the place of Arshak II's imprisonment. According to Claudia Ciancaglini and Giusto Traina, the Armenian form berd Anush is a borrowing from an unattested Middle Persian name which may be reconstructed as *anōš bard. The form Anyush is a later reinterpretation or Armenianization of the original word, identifying it with the common word anyush 'forgotten'. Ciancaglini argues that the original meaning of the name was not 'Castle of Oblivion'—a sense derived from the Armenian etymological reinterpretation—but rather 'immortal, imperishable fortress' (from Middle Persian anōš⁠ 'immortal').

Notable prisoners of the Castle of Oblivion

Arshak II, Arsacid prince, who ruled Armenia as a Roman client from 350 until 367. Captured and imprisoned during Shapur II's invasion of Armenia.

Editorial analysis

Why this record matters

The phrase “castle and political prison in 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.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 13, 2026. The linked authority identifier is Q5740020. Authority coordinates are 32.033, 49.850. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2009.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
