The Mysterious Tower

The Tower is a place from Kingdom Hearts II.

Towering atop the island floating above the skies of Twilight Town, the surrealistic, crooked tower that Sora encounters early in his adventure is owned by master Yen Sid. On Sora's first journey up the tower, it is under attack by the Heartless. Later on, it is haunted by Nobodies.

The tower itself is based on the setting of The Sorcerer's Apprentice from Fantasia.
