Marathon Oil Tower is a skyscraper in Uptown Houston. The building rises 562feet in height.[1] It contains 41 floors, and was completed in 1983 and construction only took 22 months.[2] First City Tower currently stands as the 20th-tallest building in the city. The architectural firm who designed the building was Pierce Goodwin Alexander & Linville.
The building is named for American petroleum and natural gas exploration company Marathon Oil. The company was headquartered in this building for over thirty years, until it relocated in 2021.[3] The building has since undergone a rebranding process and is now officially known as 5555 San Felipe.[4] [5] In addition Aon Corporation has its Houston offices in the tower.[6]
