Transamerica Pyramid
From the Super Mario Wiki
The Transamerica Pyramid is a skyscraper in San Francisco shaped like a pyramid. Luigi once visited it during the events of Mario is Missing! In the game he had to return the top of the Transamerica Pyramid to the landmark, as it was stolen by Koopa Troopas invading the city. Finding and stomping the Koopa Troopa that hid the artifact would allow Luigi to return it to the Pyramid. He would be rewarded 1,600 dollars for completing this task.
[edit] Pamphlet Information from Mario is Missing!
The Transamerica Pyramid on Columbus Avenue in downtown San Francisco was built in 1972. It has become a landmark due to its unusual shape. Standing 853 feet tall, the Pyramid is said to have changed the distinct shape of the city's skyline. San Francisco is very susceptible to earthquakes, so the Pyramid was built with a flexible concrete base which makes it one of the most earthquake-proof of all of San Francisco's skyscrapers.
