Magnolia Hotel, Skyscraper in downtown Houston, United States

The Magnolia Hotel is a skyscraper on Texas Avenue in downtown Houston, Texas, rising 22 floors to about 99 meters (325 feet). The building stands as part of the historic core of downtown, surrounded by other early office towers and commercial blocks.

Built in 1926 as the Houston Post-Dispatch Building, it housed the newspaper and was Houston's tallest building until the following year. In 1932 it was renamed the Shell Building when it became a regional operations headquarters of the Shell Petroleum Corporation, a predecessor of the Shell Oil Company. It now operates as the Magnolia Hotel at 1100 Texas Avenue.

The building's name comes from the magnolia, the state flower of Texas and the emblem of Houston. The hotel occupies the former Houston Post-Dispatch Building, later the Shell Building, and its address at 1100 Texas Avenue places it in the downtown office district.

The hotel sits in the heart of downtown Houston, within walking distance of offices, restaurants, and transit stops. Visitors arriving on foot or by public transport will find the location easy to navigate since the street grid downtown is straightforward.

For roughly two years in the mid-1920s, this building was the tallest in Houston before newer towers overtook it. That brief spell at the top reflects how fast the city was building upward during the oil boom years.
