Langisjór
lake
Langisjór (Icelandic pronunciation: [ˈlauɲcɪˌsjouːr̥] ) is a lake in the western part of Vatnajökull National Park, Iceland. It is around 20 km in length and up to 2 km wide, with a total surface area of about 26 km2 (10 sq mi) and a depth of 75m at its deepest point.
The lake is situated rather far from civilisation at the south-western border of Vatnajökull at an altitude of 670 m above sea level. Environmental campaigners have expressed concern at government plans to site an industrial dam on the lake.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Langisjór”, the useful work is to connect “lake” to the records capable of establishing context and consequence.
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 Jul 27, 2026. The linked authority identifier is Q283536. VIAF identifies the subject as 9256152140010911100003. Authority coordinates are 64.183, -18.250. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
