Three Gates is a song included in the Halo 3: Original Soundtrack. It can be heard during the level The Covenant and is the first movement of the Covenant Suite.

It starts with a low strings note, which is followed by the piano melody from the Halo 3 Announcement Trailer. Next comes the beginning melody of the Halo 3 E3 2007 Trailer, also a remake of the Halo 2 song Unyielding. At around 0:45 seconds, drums take over with a melody. Strings continue to play an accompaniment in the background. At 2:00 seconds, drums play a loud note, and the song Leonidas from Delta Halo Suite begins to play. Choir and strings are the main melody. This section is played at checkpoint Alpha on the Halo 3 level, The Covenant during the first Hornet battle. Its title is likely a reference to the three shield towers that the allied forces must deactivate to reach Truth and the Citadel.

It runs for 4:35 seconds.
