The ExxonMobil Building (formerly the Humble Building) was built in 1963 in Houston, Texas. At that time it was the tallest building west of the Mississippi River at 606 ft (185 m), surpassing the Southland Center 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.
ExxonMobil is the owner of the building. One of the most distinctive features of the building are the cantilevered seven-foot-wide shades (2.1 m) on each floor that protrude from the side of the building to provide shade from the daytime sun. The top two floors are dining space for the Houston Petroleum Club.
