Frozen in time at the Costa Concordia's crippled starboard side, a couple of rusty lounge chairs are tidily lined up on the balcony, a simple aluminum chair stands in a corner, while green lamps hang over the cruise ship's deck.

By some strange fortuity, despite the collision on the rocks of Giglio on January 13, the capsizing of the ship, 20 months underwater and a 65-degree rotation, the chairs and lamps amazingly stand in their original positions, as if waiting for guests to enjoy some sunshine or a coffee at the one of the cruise ship's shining bars.

But all around, it's hell.

The inside story of the daunting salvage operation will be revealed on Discovery Channel's "Raising Concordia," Friday September 20 at at 10/9c.

Stacked up furniture sticks out of broken windows and doors. Crumpled metal and grime dominate the once glorious cruise liner, while piles of chairs form a twisted mass of rusty metal. A brightly colored small table hangs from a window, while doors on the buckled lower decks slowly open and close as water flows through them.

Welcome to the dark side of the Concordia.

The 114,500-ton ship struck a rock and capsized on Jan. 13, 2012, after captain Francesco Schettino allegedly drove it on an unauthorized route too close to shore, ripping a huge gash in the hull. There are still no signs of the bodies of two people among the 32 dead who have been missing since the ship tumbled onto its side.

On September 17, during a complex, unprecedented 19-hour operation, the Concordia was pulled upright.

Seen from a distance, the cruise liner appears as a half-white, half-brown ship rising from pristine blue waters.

"It's a totally new sight. Before it looked like a white, giant, broken toy left on the shore, now it looks like a grim, haunting wreck coming back from the past," Daniela Brizzi, a resident of Giglio Porto, told Discovery News.

The Giglio inhabitants burst into long applause when, shortly after 4 a.m. on Tuesday, a foghorn wailed on the harbor signaling that the Concordia was finally brought upright.

Now, with the prospect of housing the refloated wreck for several months (at least until spring 2014 when the ship will be towed away to be dismantled in an unnamed port), many residents find the sight almost unbearable.

"The starboard side gives me such anguish that I prefer to think it was made of cardboard for some movie studio. But it's no fiction, unfortunately," Silvia Mauro a resident of Giglio Porto, told Discovery News.

Clearly visible on the 950-foot long dark side of the ship are large, caved in marks left by the two spurs of rock where the ship has rested since it capsized.

The decks of once luxurious cabins now appear compressed and flattened, with streams of rust. Ripped curtains hang from twisted windows, forming disquieting silhouettes as they wave in the wind.

"It looks like a Beirut bombed building," Angelo Gabrielli, a resident at Giglio Castello, told Discovery News.

Ironically, there is no lack of light on the dark side of the Concordia. Neon-like lamps are still on the walkways of the decks, as are the disco lights on the upper deck.

The most photographed sight, the blue words "Costa Concordia" on the capsized hull, has now disappeared. To raise the Concordia with her dark side, the symbol of the disaster is now submerged and faces the ocean floor.
