One Shell Plaza
One Shell Plaza ( OSP) is a 50 floor skyscraper at 910 Louisiana Street in Downtown Houston, Texas, United States. At its completion in 1971, One Shell Plaza was the tallest building in Houston, Texas, standing 715 feet (218 m) tall. Including the antenna tower on its top, the height is 985 feet (300.2 m). One Shell Plaza was designed by Skidmore, Owings & Merrill LLP. Associate architects of One Shell Plaza were Wilson, Morris, Crain & Anderson. Shell Oil Company, a subsidiary of Royal Dutch Shell, is headquartered in this building. The Plaza Club, on the 49th floor of the building, has dining, entertainment, and meeting facilities.

The building opened in 1971 and received a renovation in 1994.

The 170 ft mast atop the building has carried various television and radio signals since the building's completion. The mast supported 1971 start up channel 26 KVRL (TV) (later KDOG, now KRIV) and a mast that simultaneously radiated signals for eight FM stations KYND (then 92.5, now KKBQ-FM on 92.9 MHz), 93.7 KRLY (now KKRW), 95.7 KIKK-FM (now KKHH), 99.1 KODA, 100.3 KILT-FM, 101.1 KLOL, 102.1 KLYX, and 104.1 KRBE. The combiner and antenna was supplied by Electronic Research Inc. One Shell was used until the completion of the then Texas Commerce Tower and Allied Bank Plaza in 1982-1983, creating a skyscraper canyon that causes multipath distortion, and necessitated the move to the Houston antenna farm in Fort Bend County.
