The Lumen Technologies Building in Minneapolis, Minnesota was completed in 1932 and became the tallest building to be built in the city during the 1930s, 1940s, and 1950s. Named for its current owner, it was previously known as the CenturyLink Building, Qwest Building and the Northwestern Bell Telephone Building. Originally standing 346 feet (105 m) tall, the structure grew to 416 feet (127 m) with the addition of a microwave antenna "crown" in 1958, followed by the addition of a second tier of microwave antennas in 1972. It was the second-tallest building in the city after the slightly older Foshay Tower for many years, and stands slightly taller than the tower of its neighbor, Minneapolis City Hall.
