Côn Đảo (lit. 'Côn Island'), officially the Côn Đảo Special Zone (Vietnamese: Đặc khu Côn Đảo) is an archipelago in the East Sea (South China Sea), and Ho Chi Minh City's only special zone.
Geography
Situated about 185 km (115 mi) from Vũng Tàu and 230 km (140 mi) from Ho Chi Minh City, the group includes 16 mountainous islands and islets. The total land area reaches 75.15 km2 (29.02 sq mi) and the local population is about 5,000.
The islands are composed of magmatic rocks of different ages. Hòn Bảy Cạnh, Hòn Cau and Hòn Bông Lang are composed of Cretaceous microgranite rocks. The northern part of Côn Đảo Island is composed of quartz diorite and granite - granodiorite of the late Mesozoic- early Cenozoic ages and is partially covered by Quaternary marine sediments. The southern part of this island and Hòn Bà island are composed of the rhyolite and intrusive formations of unknown age. On the western slope of Côn Đảo Island, there exist groups of outcrops of diorite and microgranite penetrated by big quartz bands.
The island group is served by Con Dao Airport (IATA: VCS, ICAO: VVCS) situated on the largest island in the archipelago, Côn Sơn Island. The total size of Côn Đảo Airport is 3,792 m2 (40,820 sq ft), with one runway 1,830 m (6,000 ft) long.

Why this record matters
The phrase “special zone in Ho Chi Minh City, Vietnam” 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 Sep 19, 2026. The linked authority identifier is Q370746. VIAF identifies the subject as 170375328. Authority coordinates are 8.683, 106.606. 2 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
