The Basilica of Heaven is a temple constructed by the people of Babel which was originally intended to reach God. Existing close to the beginning of time, the temple became abandoned when the human population of Babel was converted into Umbrians. The temple is guarded by the Sphinx, who also protects Babel. It is filled with mysterious traps and mechanisms, many of which contain religious significance. Adam's first adventure took place within the confines of the Basilica.
