Reaching the top of the Prison Tower in Castlevania: Belmont's Curse requires navigating a hidden mechanic: the carpenter's crane. This crane is essential for accessing the Roof of the Tower area, where the Warrior, one of the game's initial bosses, awaits. The Prison Tower can be found on the Paris Streets map by heading north from the Gate to the Catacombs, then proceeding west.
Finding the Carpenter's Crane
While much of the tower is explorable, the path to the Roof of the Tower map is blocked. The key to progression lies with a spirit who reveals the existence of a hidden crane. This spirit is located in the western part of the Upper Tower segment. Players must swing across two yellow anchors to the west and reach a platform with a lever. To access the spirit above this lever, follow the path to the left, which is filled with traps. Players will need to quickly jump between walls to ascend, then swing to a small platform in the left corner of the room. From there, drop and time a whip swing to a purple anchor on the left, followed by another on the right.
Upon speaking with the spirit, players will find a sketch of the carpenter's crane, indicating the anchor to pull to open the path to the crane and its location. To find the crane itself, return to the lower part of the Prison Tower and proceed to the level containing the Mirror of Life room. Head west, and before entering the tower, use a purple anchor to jump from the wall to a yellow anchor. Swing back toward the tower to reach another, higher purple anchor, and then jump onto a platform.
On this platform, a yellow anchor will be visible to the right. Swing to it, then to another yellow anchor featuring a wooden hexagon above it. Swinging on this anchor three times will open the door leading to the crane. Once inside, use the crane to reach the door that leads to the Roof of the Tower, allowing you to confront the Warrior.
