- "Every town has one, the spooky house that all the kids avoid. Ours was Thornhill, the Blossom family’s mansion, with its very own graveyard."
- —Jughead about the Blossom family home[src]
The Blossom House, also known as Thornhill, is the family residence of Rose, Penelope, Cliff and Cheryl Blossom, as well as Jason Blossom before his death. It is a large mansion set on an expansive estate, that includes a cemetery.
- Jason Blossom (deceased)
- After his body is found, Jason Blossom is buried in the cemetery on Thornhill's grounds. Originally, his parents had buried an empty casket.
- The Blossom family motto, as inscribed on the mansion's front gates is "Radices Currere Abyssi" which translates as “Roots Run Deep".
- Also on the front gates are roman numberals MCMXLI, 1941, likely the year the house was built. (Also the year of Archie first appeared in Pep Comics #22)
