English: The Soo Line Building is a 19-story residential highrise in Minneapolis, Minnesota which was the tallest commercial building in the city from the time it was completed in 1915 until the Foshay Tower was built in 1929. It was built for the First National Bank of Minneapolis, a predecessor of today's U.S. Bancorp (U.S. Bank). It later served for many years as headquarters of the Soo Line Railroad, which added an iconic clock to the corner of the building's street level. For commercial purposes, it was sometimes referred to by its address, 501 Marquette. It surpassed the Metropolitan Building in height, though Minneapolis City Hall was the tallest building in the city from the 1900s decade until the Foshay was completed. The building is located across Marquette Avenue from 510 Marquette, the original Federal Reserve Bank of Minneapolis. The building was listed on the National Register of Historic Places on May 12, 2008.
