History Main / UnderwaterRuins

** ''VideoGame/SonicSuperstars'' is another underwater ruins level, where Sonic and his friends can sometimes [[UnderTheSea submerge themselves in water to get around a level]]. The Water-Chaos Emerald power can help them move around easier, being able to freely swim in the water for a short time.

* ''Anime/MacrossDoYouRememberLove'' has the sunken Protoculture city on Earth, that may or may not have inspired the legends of Atlantis. Hikaru and Misa are able to raise it, only to have the Zentradi and Meltrandi [[IncrediblyLamePun raze]] it shortly thereafter.

%%** Water Palace and Pirates' Island, the latter of which being built into a base. (''VideoGame/SonicRushSeries'')
%%** ''VideoGame/SonicGenerations'' features both {{VideoGame/S|onicHeroes}}easide [[NostalgiaLevel Hill]] in the console version, which has been retooled to be partially underwater, unlike the original level, and the above [[VideoGame/SonicRushSeries Water Palace]] in the 3DS version, with a few added gimmicks for Act 1.
** Sylvania Castle, the first level of ''VideoGame/SonicTheHedgehog4 Episode 2'', is the ruins of an ancient castle that are partially sunken.
** This is also a staple in fangames: ''VideoGame/Sonic3DIn2D'' (a [[VideoGameDemake Fan Demake]] of ''VideoGame/Sonic3DBlast'') makes [[RuinsForRuinsSake Rusty Ruins Zone]] a water level, while ''VideoGame/SonicRoboBlast2'' has Deep Sea Zone, which essentially is Tidal Tempest in 3D.

* ''Film/{{Aquaman}}'': King Atlan's tomb is located in the middle of an extensive tract of undersea ruins - probably the lost original city of the Atlanteans, although that's never stated outright.

** This is also a staple in fangames: ''VideoGame/Sonic3DIn2D'' (a [[VideoGameDemake Fan Demake]] of ''VideoGame/Sonic3DBlast) makes [[RuinsForRuinsSake Rusty Ruins Zone]] a water level, while ''VideoGame/SonicRoboBlast2'' has Deep Sea Zone, which essentially is Tidal Tempest in 3D.

** The series' lore includes the sunken continent of Yokuda, home to the ancestors of the Redguards. According to popular myth, it was "sunk beneath the sea" by a renegade band of [[TheOrder Ansei]], "[[MasterSwordsman sword saints]]" who could [[SpontaneousWeaponCreation form swords out of their own spirits]] called "Shehai", using a DangerousForbiddenTechnique known as the "Pankratosword", which they could use as a FantasticNuke. (Other accounts state that the likely cause was a much more natural type of disaster.)

%%* ''VideoGame/JakAndDaxterThePrecursorLegacy'': The Lost Precursor City.

* ''VideoGame/MonsterHunter3Tri'': Sunken beneath the waters that surround Moga Village and the Deserted Island are the Underwater Ruins, which once belonged to a now-extinct civilization. It is where [[spoiler:Ceadeus, an Elder Dragon that is threatening the peace of Moga's inhabitants]] lies, and the player's character has to repel it during battle. In ''3 Ultimate'', it's also possible to find [[spoiler:the subspecies Goldbeard Ceadeus, as well as Abyssal Lagiacrus,]] here as well during G Rank.

* ''VideoGame/SonicTheHedgehog'' seems fond of this:
** The earliest example is Labyrinth Zone from [[VideoGame/SonicTheHedgehog1 the original game]], a half-sunken ancient ruin filled with spears, floating platforms, piranha badniks, and stone bear heads that shoot fire, even when submerged. A PaletteSwap of this level serves as the third act of [[EternalEngine Scrap Brain Zone]].[[note]]Act 3 of Scrap Brain was originally intended to be a sewer level, but time constraints forced the developers to essentially make "Labyrinth Zone Act 4".[[/note]]

* ''Literature/{{Jingo}}'': Subverted. It turns out that the ornate ruins on the ascended isle of Leshp [[spoiler: were constructed underwater by Curious Squid, not above-water by people]].

* ''Frannchise/{{Metroid}}'':

* ''Anime/DoraemonNobitaAndTheCastleOfTheUnderseaDevil'' have the gang exploring the Bermuda Triangle, and the ruins of what used to be Atlantis until it's defense system, an [[AIIsACrapshoot insane AI]], wipes out all life on it.

* ''Film/{{Waterworld}}'': The flooded ruins of a modern city are seen underwater when [[spoiler:the Mariner shows Helen where he gets his dirt from]]. Presumably, there are a lot more than just that one beneath the oceans that now cover the entire Earth.

* In ''Film/GodzillaKingOfTheMonsters2019'', the title character makes his lair in a sunken metropolis that has somehow wound up in a crevasse deep within the [[BeneathTheEarth Hollow Earth]]. It was built by an ancient, forgotten civilization who worshipped him - and the other {{kaiju}} - as gods.

* ''WesternAnimation/TheFairlyOddParents'': Cosmo sunk Atlantis... seven or eight times. Eventually the residents just gave up on living on the surface and evolved into mer-people. When Timmy wishes to visit Atlantis, he ends up having to rescue Cosmo from their revenge by proving that they're actually better off safe and secluded under the ocean.
%%* ''WesternAnimation/FlipperAndLopaka'': The sunken island of Quetso.

* ''VideoGame/BanjoTooie'': much of the underwater part Jolly Roger's Lagoon is an Atlantis-like ruin, in contrast to the nautical port town on the surface.

* Similarly to the Quabbin Reservoir example (Literature), many towns along the Tennessee River were flooded by the construction of hydroelectric dams. Most of the buildings were demolished, but divers can still see the foundations of some. The [[http://www.louishelbig.com/sunkenvillagesst.html Sunken Villages]] project documents the ruins of old towns visible in the St. Lawrence Seaway along the New York/Ontario border of the US and Canada. Instead of flooding due to hydroelectric dams, in this case it's because the river was expanded into the Seaway for shipping. The invasive zebra mussel "cleaned" algae out of the Seaway in recent years, turning the formerly murky waters clear and allowing easy aerial photography of the ruins (which are now mostly foundations and roads).

* Alexandria's harbor is is just littered with ruins that have fallen into the sea/been dumped there. Some of these stones are thought to be large that they only could have come from Alexandria's legendary light house.

* Wiki/ThatOtherWiki has a list of real sunken ruins [[http://en.wikipedia.org/wiki/Category:Underwater_ruins here.]]

[[folder:Tabletop Games]]
* ''TabletopGame/CeruleanSeas'': The ruins of the drylander cities, broken and drowned in TheGreatFlood that covered the world in endless oceans, are still scattered around the sea bed for intrepid spelunkers to explore.

** You shoot down alien craft all over the world, then go to capture or kill them. This happens around underwater ruins an awful lot. The Atlateans must have had a global civilization.
