Carbide & Carbon Building

The Carbide & Carbon Building is a 37-story, 503 feet (153 m) landmark Art Deco high rise built in 1929, located on Michigan Avenue in Chicago.

[11] The exterior of the building is covered in polished black granite, and the tower is dark green terra cotta with gold leaf accents.

The use of stylized representations of leaves on the building's exterior was an intentional reference by the architects to the prehistoric origins of subterranean carbon deposits in the decay of ancient plants.

[13] According to popular myth of the era, Burnham Brothers supposedly designed the building to resemble a dark green champagne bottle with gold foil at the top.

The largest architectural firm in Chicago today and one of the major architectural firms worldwide – the world-renowned Skidmore, Owings & Merrill, aka SOM, which also has its headquarters in the Railway Exchange Building – is actually an offshoot of Burnham Brothers: Nathaniel A. Owings joined the practice in 1929 and left in 1934, and Louis Skidmore joined in 1930 and left in 1936.

[18] It is also the filming location for Bruce Wayne's building / Batgirl's lair, in Gotham City, as incorporated in the Arrowverse as part of Elseworlds, a 2018 crossover storyline among the shows, which introduced Batwoman.

A scaled-up version of the building features as a prominent landmark within the fictional city of Lost Heaven in the video game Mafia: Definitive Edition.
