What cities are associated with Hades?

Hades, the ancient Greek god of the underworld, is primarily associated with the city of Eleusis, where the Eleusinian Mysteries were celebrated in his honor. Additionally, the city of Thebes is linked to Hades through myths involving characters like Orpheus and the descent into the underworld. Though not a city in the traditional sense, the realm of the underworld itself, often referred to as Hades, is central to his mythology.
