Little Hangleton graveyard

The Riddle House Graveyard was the graveyard outside the Riddle House. It was where Cedric Diggory was killed, Lord Voldemort was reborn, and his duel with Harry Potter.

Events
In 1995, Voldemort's servant, Peter Pettigrew a.k.a Wormtail, brought a cauldron of Nagini's venom to the graveyard. Harry Potter and (unfortunately) Cedric Diggory, having being transported by the graveyard by the Triwizard Cup, which was a Portkey, saw Wormtail for a brief moment before Voldemort killed Cedric, and Pettigrew tied Harry to Tom Riddle's grave. Wormtail then took a "bone of the father", "flesh of the servant" and "blood of the enemy" and added these "ingredients" into the cauldron. Voldemort was reborn.

Lord Voldemort then summoned his Death Eaters to the graveyard, and told them about Quirinus Quirrell and the Philosopher's Stone, Wormtail and Bertha Jorkins, Barty Crouch Jr. impersonating Alastor Moody in Hogwarts, and his resurrection "from the ashes". He then dueled with Harry for a brief moment, before the reverse spell effect, Priori Incantatem, took place. The reverse echos of Cedric, Bertha Jorkins, Frank Bryce, James Potter and Lily Evans emerged from Voldemort's wand. They shielded him from Voldemort's Killing Curse, allowing Harry to grab Cedric's body, grab the Triwizard Cup, and escape from The Riddle House.
