"The seven heads are seven hills on which the woman sits."
If you are implying that Rev 17 speaks of the Roman Catholic Church, understand that Vatican Hill (Latin Collis Vaticanus) is northwest of the Tiber and is NOT one of the Seven Hills of Rome. Likewise, the Pincian Hill (Latin Mons Pincius), to the north, and the Janiculum Hill (Latin Ianiculum), to the west, are not counted among the traditional Seven Hills.
Of the Seven Hills of current Rome, five (Aventine, Caelian, Esquiline, Quirinal and Viminal hills) are populated with monuments, buildings, and parks. The Capitoline now hosts the Municipality of Rome, and the Palatine Hill is an archaeological area. Note that the Vatican hill is not one of the “seven hills” of Rome, as it is located on the opposite side of the river Tiber. So the association of the Roman papacy as the woman is not a strong argument.
I am not saying that is necessarily what you were implying. Just saying.
Often the 7 hills of the book of Revelation are assigned to Rome. So is this the only option?
NO.
