Jungle Temples are made up of cobblestone, vines and other redstone mechanisms. There are levers you need to pull to open up a secret room. There is a 2 chests is the Temple: One in plain sight when you go down, guarded by a trap with tripwire. The other chest is in a secret room, and to find a code by pulling the levers.
StructureEditJungle Temples have a trap inside, and looting the Jungle Temple (taking all the chests with you and collecting all the redstone) can give you easy redstone, if you know a seed with a Jungle temple close by the spawn. There are Dispensers in shooting arrows, so it is good to look on the ground in a Temple, if you see tripwore, follow it and it will lead to a dispenser with 9 arrows.
