The Ruins of Nosti (more commonly referred to as The Church Cave) is a Cave underneath a ruined building on the Scorched Earth map. The ruins above are a forgotten city full of domed buildings and pillars in the south east of the map in the dunes. The ruins themselves are notable as being featured as the setting for many of this ARK's Explorer Notes, which among other things chronical the city's rise and fall. The entrance is inside what many players call the church, one of the larger ruined buildings.
The cave that is the Ruins of Nosti begins with a descent down beneath the surface. This location, dubbed as the entrance, consists of the Church all the way down to where the path splits into two, where it then becomes the descent.
The 
Artifact of the Destroyer and a 
Scorched Sword Skin can be found in the Artifact crate.
This is easily the most dangerous cave in Scorched Earth between the jumps over a bottomless void (500,000 damage to anything that falls in) and the combination of some of the most dangerous creatures—including large swarms of Onycs and 
Mantis. Survivors should be well-prepared before tackling this cave. Mega Rabies will come from the 
Onyc, so make some 
Lesser Antidote beforehand. However there is not quite the variety of creatures here than in other caves, but don't take this as a sign to underestimate the cave itself.
Tek Armor could be used to fly through the cave with ease. Provided you have the

Climbing Picks and a 
Glider Suit Skin could help too, but use it with caution.
Zip-Line Anchors and a Zip-Line Motor Attachment could help with your first and subsequent runs. You'll need 
Gasoline to use it.Mantis — Uses whatever weapon it holds, so its damage depends on what it picked up, and it is fast. 
Rubble Golem — A 
Rock Elemental fragment. Untameable, and it ignores small-arms fire. 
Arthropluera — Its ranged acid attack damages armour directly — primitive Flak breaks in one or two hits — and armour damage cannot be repaired if the piece is destroyed. 
Araneo — Webs you in place from range, which stops you kiting and stops a mount fleeing. Its bite applies torpor. 
Titanoboa — Applies heavy torpor per bite and is quiet enough to reach you before you see it. 
Megalania — Climbs walls and ceilings, so it attacks from above where a mount cannot follow, and its bite applies a stacking torpor. Onyc — Attacks in numbers, drains stamina, and is small enough that most mounts cannot hit it.
