Derry is a fictional town in the U.S. state of Maine that has served as the setting for a number of Stephen King's novels, novellas, and short stories, notably It.

[4] Besides the oft-used trinity of Derry, Castle Rock, and Jerusalem's Lot, King has created other fictional Maine towns, including Haven in The Tommyknockers, Little Tall Island in Dolores Claiborne and Storm of the Century, and Chester's Mill in Under the Dome.

[7] The synagogue appearing in It Chapter Two was actually the Congregation Knesseth Israel in Toronto, while the Derry High school exteriors were filmed at the Mount Mary Retreat Centre in Ancaster, Ontario.

In the 2017 adaptation and its sequel, 29 Neibolt Street acts as the primary entrance to It's lair and the scene of the Losers Club's first real confrontation with It.

In 11/22/63, Jake Epping has a conversation with young Richie Tozier and Beverly Marsh from the novel It near the Barrens in September 1958, shortly after The Losers defeated It for the first time.

Following an encounter with the Crimson King himself, Ralph Roberts and Lois Chasse force Deepneau to crash the plane in the Center's parking lot.

In 1906, despite every machine in the works having been shut completely down, the Ironworks inexplicably exploded, killing a group of 88 children and 102 total people who were participating in an Easter egg hunt.

In the 2017 adaptation, Ben Hanscom first encounters It in the form of a headless child that was among the victims of the Kitchener Ironworks incident.

Jake finds a pile of gnawed bones and a tiny chewed collar with a bell on it inside a fallen chimney.

In its earlier days, it remained unlocked so that patrons of an adjoining park could climb a spiral staircase around the tank to look out over Derry from the top.

After the grown-up Losers Club kills It in the second Ritual Of Chüd in 1985, a huge storm ensues, destroying many buildings and landmarks in Derry, including the Standpipe.

In Dreamcatcher, Mr. Gray drives to Derry to find the Standpipe, only to discover a memorial featuring a cast-bronze statue of two children and a plaque underneath, dedicated to the victims of the 1985 flood and of It.

Ben Richards, the novella's protagonist, arrives here by car and is allowed to board a "Lockheed GA/Superbird" by bluffing that he has enough plastic explosive with him to blow up the entire complex.
