For more than four decades, from 1931 until 1972, the 1,454-foot Empire State Building was the tallest building in the world. At the time, it was hardly believed that it was possible to build anything above 1,000 feet.

Fast-forward to 2021, and in the rankings of today’s tallest human-made structures, the Empire State Building doesn’t even make the top 40. It’s not even in the top five in its home state.

To determine the tallest building in every state, 24/7 Tempo reviewed data from several sources, including the Council on Tall Buildings and Urban Habitat. Only completely finished buildings were considered.

Iowa’s tallest building is the 801 Grand. Located in Des Moines, the 630-foot human-made office building has 44 floors. Construction was completed in 1991.

With few exceptions, the tallest building in a state is in its largest city. Most are office buildings, several are hotels and casinos, and a couple are government buildings.

For many years, the U.S. has dominated the world skyscraper rankings. Now, many of the world’s tallest buildings are in Asia and the Middle East — these are the 50 tallest buildings in the world.
