Mount Olympus is home to the Greek gods. It resides on the 600th floor of the Empire State Building in New York City. Every Winter Solstice, the demigod children of the gods gather in the throne room for festivities. This is the only time Hades leaves the Underworld to visit his family. The twelve Olympians have thrones in the throne room and stand at 12ft tall, but can alter their appearances and height.
