ExxonMobil Building

The ExxonMobil Building (also known as Exxon Tower, and formerly as Humble Oil Building) at 800 Bell Street in Houston, Texas is a 45-story, 1,200,000 sq ft (110,000 m2) skyscraper built in 1963, designed by Welton Becket & Associates. The building is known for its “fins” which protrude from the bui

lding’s exterior to provide shade from the sun. At the time of its construction, it was the tallest building west of the Mississippi River at 606 ft (185 m), surpassing the Republic Bank Tower in Dallas (the previous record holder). It remained the tallest building west of the Mississippi only until 1965, when Elm Place was built in Dallas. It was listed on the National Register of Historic Places in 2025.
