The Gateway Arch (also known as the St. Louis Arch) is a national monument in Missouri, USA.

The vision of renowned architect Eero Saarinen, the Gateway Arch commemorates Thomas Jefferson and St. Louis’ role in the westward expansion of the United States. 

The Lightning Thief
Percy, Annabeth and Grover visited the Gateway Arch because Annabeth wanted to and as she might never get the chance to come again. When Annabeth and Grover is going down the elavator, Percy is atacked by Echidna and her Chimera. Percy got poisoned, and was forced to jump out of the arch, to the river below, as he was dying, and in the hope that the rest of the people in the arch would survive. Since Percy is a son of Poseidon, he didn't get any injuries when he hit the water, but rather opposite. percy was healed from his poisoning in the water. He meets a Nereid who tells him to go and visit the Ocean before he goes into the Underworld.

The Last Olympian
The Gateway Arch is seen once again while Typhon headed across the United States to The Empire State Building. This was seen in Annabeth's shield.



The Son of Neptune
After Frank and Hazel go to find Percy who had fallen off a glacier, he was sitting on a piece of ice waiting for them to return (and mildly annoyed it took them so long). When they make a comment about how far he fell, he claims it was nothing, and he fell at least twice as far from the St. Louis Arch.
