The Clock Tower is an area within the Castlevania series, perhaps the most infamous of them. It has been featured in almost every game since the first. It has also been referred to by the names of the "Mechanical Tower", "Tower of Death", "Machine Tower", and "Clock Tower of Untimely Death".
Most Clock Tower areas feature the enemy Medusa Heads, generally in two varieties: a blue head with green hair, and another with a gold head and brownish-red hair that can turn the player to stone upon contact; depending on the game, the Bestiary entries for them may be separate (Harmony of Dissonance), or lumped together. In Order of Ecclesia, the Gorgon Head was added, a rarer, silver Medusa Head. Although it had all of the same powers as the Gold Medusa Head and nothing more, it dropped the Fidelis Medusa glyph.
Death, the grim reaper, Dracula's confidant, typically resides in this area, though in some games, he is encountered in other, usually underground areas as well. Recently (Portrait of Ruin), Death's servants Slogra and Gaibon have appeared here as well. Other common enemies include the Harpies and other sorts of flying foes to increase the difficulty of traversing the area's many obstacles. Of note, Dawn's Clock Tower is not home to Death, but to an enemy named Zephyr, whom appropriately has the ability to stop time. Circle of the Moon features a boss called Iron Golem but since the castle in which the game takes place is not Dracula's this instance is not as odd.
It is also where you fight, and have the option of gaining as an ally, Grant in Dracula's Curse.
Most Clock Tower areas feature moving platforms in the form of gears, as well as spikes. While the gears move the character slowly, becoming petrified by a Medusa Head prohibits movement for a period of time, and greatly increases damage taken. Occasionally, the spikes and gears are used together, for example, if the player stays on the moving gears, they will be pressed against a spike-lined wall, dealing immense damage. In Super Castlevania IV, some of the gears fall off and try to hit the player. In Dawn of Sorrow, a few new traps were added; for example, a rotating spike fan and pistons that rise to push the player against the spike-lined ceiling.
The other two GBA games (Harmony of Dissonance and Circle of the Moon) have differently designed Clock Tower-esque areas. Circle of the Moon has no area named Clock Tower at all, though encountered somewhat early in the game is the Machine Tower, utilizing Clock Tower music from previous games and employing similar features.
Harmony of Dissonance's Clock Tower is perhaps the weakest in the series. There are few enemies (only Harpies and Gold Medusa Heads), and the gears are used to little effect, despite the easy-to-solve puzzle involving them.
The Clock Tower is usually in the (upper) right of the castle, though in a few games, it is not. Typically, it is the highest section of the castle, and as such, usually leads to Dracula's area via a large stairway.
At the very top of the Clock Tower, there is usually a room in which the background displays the 'outside' of the castle, such instances are somewhat rare in Castlevania games.
The area usually can be seen in the background on the stairway leading to Dracula's keep. Two such towers were seen in Lament of Innocence, suggesting there may be multiple towers.
Generally, the Clock Tower music is the most distinct in the game, Castlevania 3 is a prime example of this, several remixers on OCRemix and the Video Game music band The OneUps incorporate the Clock Tower theme into their songs. Even the Castlevania series does this ; Circle of the Moon's Machine Tower area uses the Clock Tower theme from Castlevania 3. The music is somewhat "organ heavy" in most games.
