Set in the summer of 1922, most of the story takes place in the fictitious New York towns of East and West Egg, Long Island, and in New York City.
Nick Carraway, who has rented a cottage in West Egg next door to the rented estate where the fabulously wealthy Jay Gatsby lives, renews his acquaintance with his cousin Daisy Buchanan and her husband Tom, who live in East Egg. When Gatsby wishes to meet the charming Daisy, whose voice rings like the sound of money, he selects Nick as his confidant.
The glitter and intrigue of the 1920s permeate the story, and the details of the setting are important to the development of the theme.
Gatsby’s mansion
Garish, multilevel home located on “West Egg.” The narrator Nick Carraway describes it as colossal, as ostentatious as it is roomy. Situated on forty acres, the mansion is the site of numerous glitzy and riotous parties thrown by Gatsby, hoping to pique Daisy Buchanan’s interest. The mansion, however, is much more than a lure for Gatsby’s long lost love; it is a symbol of the man himself and his dream of materialism as a vehicle to success both literally and romantically. Gatsby’s home parallels his persona—grand, mysterious, and richly adorned. It is the emblem of a successful businessman and the symbol of what he hopes to recover in Daisy and her love. The mansion is also a representation of a shortsighted American Dream: that material success, in and of itself, will bring one status and happiness. Unfortunately, the dream is based on hollow underpinnings, on the vacuous Daisy and the misguided concept that large amounts of money can be made and used without responsibility. The mansion represents the grandness and emptiness of the 1920s boom: Gatsby justifies living in it all alone by filling the house weekly with "celebrated people." Conversely, the mansion serves also as a symbol of Gatsby’s vision, aspiration, idealism, and belief in the American Dream of the self-made man. Thus, it is simultaneously a symbolic representation of the “great” Gatsby and of the flawed one. Ultimately, Nick Carraway describes the mansion as “that huge incoherent failure of a house.” The mansion exists as both a vision and failure of such a vision.
East Egg and West Egg
Fictionalised opposing peninsulas of Long Island Sound described as resembling a giant pair of eggs. They are contrasted in terms of fashionableness, colour, and type of wealth. The East Egg mansions glitter along the water; they are more chic and are representative of older, Eastern, inherited wealth. The West Egg residences are more derivative and imitative, representative of the nouveau riche, affluent newcomers not yet accepted into the highest echelons of wealth. It is Gatsby’s habitation in West Egg that denotes his aspiration to a social status that seems unattainable. The Buchanans, who reside on East Egg, represent the arrogance of an exclusive clique who attend Gatsby’s parties and share in the fruits of his wealth but who essentially despise him. Tom Buchanan, who has inherited his fortune, does not value it in terms of the traditional American ethics of hard work, integrity, fairness, and success coupled with responsibility. The two Eggs also represent the larger framework of an East symbolic of European antiquity, old money, and corruption, and a West symbolic of independence, new money, and the pioneering spirit. Certainly Nick Carraway values Western ideals over Eastern, and at the conclusion of the novel he returns, in a westerly direction, to the traditional and conservative Midwest whence he came. Nick describes the novel as a book about Westerners, a "story of the West." Tom, Daisy, Jordan, Gatsby, and Nick all hail from places other than the East. The romanticised American idea of going West to seek and make one's fortune on the frontier turned on its ear in the 1920's stock boom; now those seeking their fortune headed back East to cash in. But while Gatsby suggests there was a kind of honour in the hard work of making a fortune and building a life on the frontier, the quest for money in the East is nothing more than that: a hollow quest for money. The split between the eastern and western regions of the United States is mirrored in Gatsby by the divide between East Egg and West Egg: once again the West is the frontier of people making their fortunes, but these "Westerners" are as hollow and corrupt inside as the "Easterners."
Valley of Ashes
An area halfway between New York City and West Egg, the Valley of Ashes is an industrial wasteland covered in ash and soot. If New York City represents all the "mystery and beauty in the world," and West Egg represents the people who have gotten rich off the roaring economy of the Roaring Twenties, the Valley of Ashes stands for the dismal ruin of the people caught in between. Generally considered to be Flushing in New York City’s borough of Queens, this place exists as a grey, dead, "powdery" area—even the homes seem to be composed of ashes—passed by motorcars on their way to New York. Here Myrtle and George Wilson live and operate a garage and gasoline station. The valley is a metaphoric representation of the wasteland the American Dream becomes when ethics and morals are disassociated from it. The valley is also the locus of those, such as George and Myrtle, who are victimised by the arrogant wealthy who base their lives on pleasure, avoidance of boredom, and dishonesty. If East and West Egg are two renditions of attainment of the American Dream, the Valley of Ashes is its demise. Literally it is the site where Daisy kills Myrtle, without compunction, and George decides to murder Gatsby. Finally, overlooking the valley are the giant blue eyes of Dr. T. J. Eckleburg, who stares down on the ashes from a billboard. A central symbol of guilt, judgment, and God, it invests the valley with a moral intensity that allies the novel with existential themes and statements about the moral bankruptcy of the modern world, a vast grey, ashen wasteland.
New York City
Certain integral scenes take place in this city and often entail irresponsibility, adultery, violence, and drunkenness. New York is where Tom Buchanan takes his mistress, where Nick witnesses Tom brutalising her, where Gatsby reveals his illicit love affair with Daisy, and where a lot of alcohol is consumed. Symbolically, the city represents careless consumption and irresponsible immorality. New York in the 1920’s was a glittering den of writers, socialites, wealthy entrepreneurs, and other moneyed persons who were known for their extravagance and excesses.
e.g.
The valley of ashes is “nowhere,” a place to be driven through on the way to the “somewhere” by characters from both East and West Egg. The "ashes" have connotations of death and could be an allusion to T.S Elliots's modernist poem 'The Waste Land', where themes of disillusionment and despair are explored. As such, the valley could be symbolic of the insidious underbelly of New York in the 1920s, and the facade or even death of the American Dream, whereby only the corrupt and unscrupulous could actually attain it, leaving the rest of society to scrounge for survival in the bleak, dark and "ash[y]" places: they are left with nothing and "nowhere" but ruin, misery and death.
The "grotesque gardens" is an alliterative and paradoxical description that conjures images of an unnatural world. A garden is typically beautiful, but this one has been warped into something monstrous. This may be a consequence or bi-product of unchecked decadence and indulgence by the wealthy who are able to quickly drive through the toxic-sounding "powdery air", while the underprivileged and underclass are forced to "move dimly" through it. The imagery of this unpleasant environment, in contrast to the mansion settings of Gatsby and the Buchanans, works to highlight the widening class separation in 1920s America. It is also here that Myrtle Wilson is “run down like a dog” by Daisy Buchanan. Careless drivers become a metaphor for the demoralised world of wealth and privilege inhabited by people such as the Buchanans.
Fitzgerald clearly delineates class difference through his employment of this and other juxtaposing settings, like East and West Egg.
