Forest Temple

In Ocarina of Time
Deep within the Sacred Forest Meadow in the Lost Woods lies a temple inhabited by many fierce foes. It's an eerie, complex temple filled with strange puzzles and bewilderments that may come to shock you; such as an array of switches which invert hallways. Most of it's rooms and cooridors are covered with moss and vines and hold enemies like the Skulltula and Deku Baba. The temple has also recently been home to the Four Poe Sisters that lurk deep inside the temple and guard the way to it's master. You must hunt down and destroy them to complete the temple. It is also one of the few dungeons that let you change the temple, like flipping hallways. The temple's music will also become a monster of its very own with its eerie, but beautiful tune and unnatural sounds. It's also the first temple where you meet the dreaded Wallmaster in OoT, and its boss is the fierce Phantom Ganon. Link journeyed here to save his childhood Kokiri friend Saria, only to awaken her as the Sage of Forest. Her power helped Link continue on his journey to free the other imprisoned sages.

Trivia
The Forest Temple is known as the topsy-turviest level in Zelda history, followed by the Stone Tower Temple in Majora's Mask.

The dungeon's layout design shows that the temple exterior is shaped like a dome.

In Twilight Princess
The Forest Temple is the first dungeon in Twilight Princess. It is housed within a massive tree in Faron Woods, which may be theorized to be the dead remains of the Great Deku Tree. It houses the Gale Boomerang, which is used to defeat it's boss, the Twilit Parasite Diababa.

The Gale Boomerang is used inside the Temple to manipulate wind powered switches and bridges, allowing Link to access rooms deeper within the dungeon. Monkeys have been imprisoned in various locations throughout the Temple by their "chief", the mini-boss Ook; they must all be freed in order to gain access to the room of the main boss.

The temple is different from the Forest Temple in Ocarina of Time, in that it is has only one level as opposed to multiple floors. The first room of this temple is notably similar to it's Ocarina of Time counterpart. The Forest Temple is also similar to the Woodfall Temple in Majora's Mask in that a lot of the rooms seem to be very swamp-like.

It is reasonable to hypothesize that the Forest Temple within Faron Woods is formed from the remains of the Great Deku Tree.
