Archaeologists have discovered a Roman cemetery from about 300 A.D. in suburban Copenhagen with about 30 graves, a newspaper reported Wednesday.

"It is something special and rare in Denmark to have so many (ancient Roman) graves in one place," archaeologist Rune Iversen was quoted as saying by the Roskilde Dagblad newspaper.

The graveyard's exact location in Ishoej, southwest of downtown Copenhagen, was being kept secret until the archaeologists from the nearby Kroppedal Museum have completed their work, the newspaper wrote. No one at the museum could be immediately be reached for comment.
