One Metropolitan Square, Office tower in downtown St. Louis, US
One Metropolitan Square is a 42-story glass and steel tower in downtown St. Louis. The building rises 180.7 meters and stands as the tallest structure defining the city's skyline.
The tower was completed in 1989 as a major anchor for downtown St. Louis's revitalization. Architectural firm Hellmuth, Obata and Kassabaum designed it during a period of economic growth in the region.
The building houses longstanding law firms and design studios that anchor St. Louis as a business center. The restaurant at the top serves as a meeting place for professionals and offers views across the city.
The building sits near major highways and is easily reached by car. It stands in the business district where parking and public transit options are available.
In May 2014, an unmanned aircraft collided with the building, prompting local authorities to investigate. The incident briefly thrust the tower into discussions about drone safety in urban areas.
