Do you mean wreck photos? The glass dome imploded
when water cascaded into the ship as it was
sinking. You can observe a representation of this
situation in the 1997 movie about the Titanic.
The dome was covered by a protective structure, (probably most made of timber, I fancy). It would be plain bad design to have a glass structure covering a great big hole in the deck. One mishap and kersplosh!
The dome was enclosed by a cover, topped with a
beveled roof of square windows, allowing diffused
sunlight in through the windows. The dome itself
was frosted or transluscent glass. At night, the
dome was lit by lights hidden by a lip around the
base of the dome.

You can see the glass dome wenn you look good.
It isn't round but a square. Thats why the dome is covered with a structure. The lights come in true the square "box" on boat deck and shine right into the a deck en boat-deck frontstairs

I have two questions about the staircase...

If the glass dome had wrought iron decorative pieces inlaid in each pane, wouldn't it stand to reason that on Titanic, since all of the metalwork is still present, wouldn't pieces of the dome's iron pieces still be either on the collapsed dome or littering the floor?

Also, I've seen numerous reports; in the Cameron movie, the grand staircase is flooded comletely (the clock and cherub are both submerged) and people smash through the boat deck windows, THEN the dome smashes in from above. However on page 135 of "Titanic: An Illustrated History", it shows water breaking through the A-Deck windows, coming around the corner on A-Deck, going down the stairs past the clock, and breaking through the dome. The staircase looks barely flooded; the cherub statue and the stairs leading up to the clock from A-Deck are still dry, but water's coming in at all directions... Which scenario is true?

Yes, it would stand to reason that the wrought iron would be lying at the bottom of the pit that was once the forward Grand Staircase, and yet there is nothing there. That's how the theory about the staircase floating out the dome when it flooded got started. The different sections of staircase contained an innerworking made of iron. Had the staircase been consumed by wood-eating organisms, that innerworking would still be somewhere at the bottom landing. And yet there's nothing. But this is just one theory; perhaps someone else can help you out here.

As for which scenario is true, it's pretty much impossible to say with any amount of certainty. I generally imagine it happening as shown in "Titanic: An Illustrated History", but then there's the rumor I mentioned above about the staircase floating, breaking apart, etc. It's a mystery I don't see ever being solved.


I would say that the Cameron depiction is the most accurate. The Marschall painting (with all due respect to the exceptional painter) seems like a cool picture, but rather unrealistic. For the dome to have shattered just as water was coming through the A Deck windows, the wave would have had to be (and this is just a rough estimate) 10'-15' high!

But who knows

Dome in Titanic Exhibit in CA Science Ctr is flattened out, compared to what it should be (although the rest of the staircase is to scale). Question: From the base of the dome to the peak, what should the actual height be?
