The Graveyard After Voldemort killed his father and paternal grandparents, they were buried in the graveyard by the church in Little Hangleton. This, then, is also where Harry was taken by Portkey, saw Cedric Diggory killed and Voldemort reborn, and duelled Voldemort in 1995.
Riddle House Though few wizards realize it, the Riddle House holds an important place in wizarding history. Located on a hill overlooking Little Hangleton, it was the home of Voldemort's grandparents, and the place where his father, Tom Riddle, lived both before and after Voldemort's birth c. 1926.
The summer after Tom Marvolo Riddle's fifth year at Hogwarts (c. 1943), he discovered that his mother's family - the Gaunts - lived in a house across town; upon arriving there he learned of his father and grandparents and murdered them in their drawing room. Their bodies were soon discovered by the family maid. Frank Bryce was originally implicated in the crime by Muggle police; wizarding authorities blamed Morfin Gaunt.
Ownership of the house changed hands several times in the following years, but nobody stayed for long as they all agreed it had "a nasty feeling about it," and we don't know who owns it now, though the Muggles in town believe the owner is a wealthy man who keeps it "for tax reasons." Whether the owner is a Muggle, a Death Eater, or Voldemort himself, it has been sitting abandoned for years; the inside now has a "smell of decay" and a layer of "dust that lay thick upon the stone".
In the summer of 1994, Voldemort returned to the house with Wormtail and Nagini to use it as a makeshift headquarters. The night they entered the house, Frank Bryce saw light on inside and came to investigate; it was then that Voldemort murdered him. Voldemort probably remained there for some time but we don't know for sure. When he regained his body the following year, it was in the nearby town graveyard.
