Very important; the "Sarcophagus" discovery card from the Hidden Passage in Middle Rome Dungeon is DIFFERENT from the "Sarcophagus" card given my the map from Archives! ! ! The card from Rome has 4 diamonds, while the card from the map has only 1!

You may enter this dungeon at any time via the Church in Rome. The enemies within are extremely high level, however. It consists of two floors:

Upper Floor (available at the start)
Middle Floor (requires Sarcophagus discovery which Kossmynn describes in the comment above -- all fleet members must have the discovery or Middle Floor remains inaccessible)

Seems the secret passages % rate are related with the speed/ how many devices you activate in the room, right?

I tryed to activate all devices and as fast as possible and eventually i felt in a room full of "Soul of Coliseum" enemyes. They glowed purple.

Hard fight.

Loot was junk, just trade goods.

The best loot i found there, in Rome church dungeon, are the +2 art robes. Nice for adventure alts. But they are in a room without any enemy and you have to unlock all the devices there without failure.

Oh, the sparkling and splendid chests are a plus too. The easy acess and the challenging battles make this dungeon a more enjoyable farming of these chests than Siberia, imo.

I'm afraid this isn't quite as comprehensive as my usual work; my apologies, but of all the UWO dungeons, this is one which I've spent the least amount of time in so I am relying more on other sources rather than personal experience for some of the item/trade good drops. All data was compiled from the following sources:
