I don't know if people have seen this.

Intriguing. The fortress is ascribed to the Urartu civilisation (c.9th-7th centuries BC) but the lake in which it is found is considered to have been around for 600,000 years.
That said, Lake Van, despite having no outlet, has been subject to very considerable fluctuations in extent and hence depth. It is thus quite conceivable that the location of the fortress was dry land at the time of building - and quite hard to see how it could have been built otherwise.
A little more context on the underthewaterness from the National Geographic's version, at https://news.nationalgeographic.com/2017/11/underwater-fortress-urartu-lake-van-turkey-archaeology-video-spd/ :
QuoteThe archaeologists believe rising lake levels slowly submerged parts of the city over time. Large village ruins from this period can also still be found around the lake's edges, above the current water level.
Surely they were Yorkshiremen, living in paper bags eating broken glass, beaten every day and glad for a good thrashing.

And complaining about it being always wet?
We lived in't ruin at the bottom o' lake, but tell that to young people today and they won't believe it?
But post it on Facebook or Twitter and it is instantly a #FACT :P
Ay, that's what we were when water came in through roof.
