The Chaos Temple (AKA Zamorak Temple) in the Wilderness is a Temple of Zamorak located around level 10 Wilderness, north of Varrock. The temple is accessible only from the north, as the entire building is near-completely surrounded by molten lava. It contains many spawns of bones. Free players may use these bone respawn points at a lower prayer level to raise Prayer, especially if the player has low combat and cannot efficiently raise prayer from killing big bone dropping monsters such as hill giants. There is a trapdoor behind the altar that is part of the Defender of Varrock quest.
Even after the wilderness update, the Chaos Temple is a dangerous location. Apart from being a Multi-combat area, a nearby volcano constantly shoots out flaming rocks that do minor damage to anyone nearby. Also, Revenants may pop up at any time. Revenants that teleport here head towards the entrance to Bounty Hunter and then to the Graveyard of Shadows; a patrol route that could be used by Revenant Hunters. Also note that although Revenants patrol the area, they rarely, if ever come into the island and temple itself, effectively making it a fairly safe spot. Every once in a while, a Level 105 Revenant Ork will appear right outside the temple, but cannot attack most players as the temple is only in level 13 wilderness. Very rarely, level 38 Revenant Goblins can spawn in front of the altar, usually only 1 or 2 of them. However, as many as 4 Revenant Goblins may spawn there.
This location has been used historically as a place to mount ambushes, due to its popularity as a Prayer recharge point and as there is only one entrance or exit to the temple. This gave large groups the advantage over players trapped within the lava moat, as it was difficult to escape a deliberate attack by running. It was also a very popular place for 'death matches': a set battle between two individuals with certain rules and handicaps.
The pattern on the floor hints that the temple may once have been dedicated to Zaros, which is plausible given that many of his fortresses and outposts in the second age were in what is now the Wilderness, and were destroyed and/or aligned to different Gods during and after the God wars.
