The Door of Orpheus is one of the two major entrances to the Underworld. It is located in New York City, specifically the Southern Area of Central Park. It was created by Orpheus after he lost his wife, Eurydice, and tried to get her back from the dead, however he was unsuccessful. He created it by using his skills in music, and opened the path straight into the Underworld.
Nico di Angelo and Percy Jackson use this door to enter the Underworld so Percy can bathe in the River Styx. They get help from Grover Underwood, who plays his pipes and opens a tunnel in the rocks big enough for Nico, Percy, and Mrs. O'Leary to crawl through. This is due to the fact that Orpheus used music to open a new path into the Underworld to get his wife back into the mortal world.
