Fortifications of Diyarbakır
fortress in the city of Diyarbakır, Turkey
The Fortifications of Diyarbakır are a set of fortifications enclosing the historical district of Sur in Diyarbakır, Turkey. They consist of an inner fortress, the citadel, and an outer ring of city walls.
The main gates of the city are: Dağ (Mountain) Gate, Urfa Gate, Mardin Gate, and Yeni (New) Gate. The walls come from the old Roman city of Amida and were constructed in their present form in the mid-fourth century AD by the emperor Constantius II. According to Armenian historian Movses Khorenatsi, the fortifications and powerful walls of Amid-Diyarbakir were built in the middle of 6th century BC under Armenian King Tigranes of and during the Yervanduni (Orontid dynasty). They are the widest and longest complete defensive walls in the world after only the Great Wall of China (the Theodosian Walls for example are longer in length, but are not continuous).
UNESCO added the building to their tentative list on 2000, and listed it along with Hevsel Gardens as a World Heritage Site in 2015, under the designation Diyarbakır Fortress.
History
Diyarbakir's walls were first built in 297 AD by the Romans, who had colonized the city in 230 AD. In 349 AD the walls were significantly expanded or reconstructed under the order of Emperor Constantius II. Over the next 1500+ years, these walls were expanded and reconstructed using volcanic rock from the surrounding region. The site includes remains from the Hurrians, Romans, Abbasids, Sejuks, Artuqids, Aq Qoyunlu, Ottomans. The city is considered to have a "multi-cultural, multi-lingual, and multi-culture character".
The walls were expanded and restored during the Byzantine period, particularly under Justinian I (6th century).

Why this record matters
The phrase “fortress in the city of Diyarbakır, Turkey” 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 strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q7060882. Authority coordinates are 37.911, 40.227. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2000, 2015 and 1500.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.
