Are you speaking of the city sitting on seven hills. If so, then it is seven hills as it literally reads. That place is one of three and the Vatican is one of them.
So Rome has TEN KINGS sitting on its 7 hills, and you think that's what the Rev.17 Chapter is pointing to? NO... the
"seven mountains" meaning seven hills is an old THEORY about Rome. It completely... gets away from what Rev.17 shows where the Harlot sits.
I've already posted this twice, but here are those relevant Bible Scriptures that DEFINE what the
"seven mountains" are upon which the Harlot sits. And it is these... Scriptures you must use in that theory to try and prove that this is about Rome... but can you? I say no, you cannot.
Rev 17:9
9 And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth.
The symbolic Babylon Harlot sits upon the
"seven mountains".
Rev 17:1
17 And there came one of the seven angels which had the seven vials, and talked with me, saying unto me, Come hither; I will shew unto thee the judgment of the great whore that sitteth upon many waters:
KJV
Those "
seven mountains" above are FURTHER DEFINED to be symbolic "
waters".
Rev 17:15
15 And he saith unto me, The waters which thou sawest, where the whore sitteth, are peoples, and multitudes, and nations, and tongues.
KJV
And those "
waters" upon which the whore sits are then DEFINED to mean "
nations". Is Rome about plural "
nations"? No, but the idea of those
"seven mountains" the harlot sits upon do represent nations,
kingdoms. That cannot be the hills of Rome.
So the idea of hills has no association with the Bible text there. The fact is that the "
waters" upon which the Harlot sits is NOT about the Harlot's location, but about its POWER over those
"peoples, and multitudes, and nations, and tongues", pointing to the whole earth. Does Rome today have power over all nations, peoples, and tongues? Nope. Some attempt to argue that point, but it should be obvious that Rome today does not have power over all nations and peoples.
Then there's more defining Scripture there in Rev.17...
Rev 17:18
18 And the woman which thou sawest is that great city, which reigneth over the kings of the earth.
KJV
By that above verse, one should immediately notice about the Harlot reigning over the kings of the earth. That means over the idea of 'kingdoms'.
That "
great city" label is used 10 times in the KJV. Below it is referring directly to where our Lord Jesus was crucified, which means
JERUSALEM...
Rev 11:8
8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.
KJV
In Revelation 21:10, that "
great city" label points directly to the
new JERUSALEM coming down from God out of Heaven. So that's even more Scripture proof that JERUSALEM is the "
great city" label in Revelation, either the one on earth today, or the future New Jerusalem of Rev.21. But how... do we know which JERUSALEM is being pointed to in Revelation 17 & 18? That actually should be very easy to figure out because of what that Babylon Harlot does at the end of this world,
AND...
In Ezekiel 16 is where God first used that HARLOT label for JERUSALEM when it fell away to idol worship. He even covers the point when the Jebusites once owned Jerusalem in false worship, when it was called the city of Jebus. That gives a Bible Witness about JERUSALEM being labeled a HARLOT in its past history under idol worship.
And in a state of idol worship is how JERUSALEM on earth will be prior to Christ's return. Christ has even warned His servants for the end of this world to get out of JERUSALEM when they see the
"abomination of desolation" idol setup there in the holy place, meaning in a rebuilt Jewish temple in Jerusalem for the end. (And today's Jews already have the materials ready to build their 3rd temple in Jerusalem.)
Therefore, disregarding all the above Bible Scripture evidence pointing to JERUSALEM on earth for the end of this world, and instead trying to insert Romanish theories, is like tearing out those above Bible Scriptures from God's Word, and instead inserting men's doctrines about Rome in their place instead.
Some brethren simply have yet to understand that toying with God's Word by trying to change it and insert foreign meanings into it can mean The Holy Spirit not giving the believer understanding in His Word. He can cut it off for mistreating His Word with supplanting it with men's doctrines.
