Reunion Tower, also known locally as "The Ball," was completed on February 2, 1978, along with the Hyatt Regency Dallas at Reunion,[5] as part of an urban redevelopment project that also renovated the historic Union Station, which today services Amtrak, Dallas Area Rapid Transit, and the Trinity Railway Express to Dallas/Fort Worth International Airport and Fort Worth.

[6][7] When it first opened, the tower included radio station KOAX-FM, now KRLD-FM 105.3 FM, once owned by Westinghouse Broadcasting ("Live twenty-four hours a day from five-hundred feet above the city").

Each shaft's outfacing wall is made up of glass panels, providing tourists views of the city during the 68-second elevator ride to the top.

For example the globe is illuminated with festive animations during the winter holidays, lit green for St. Patrick's day and red white and blue for patriotic events.

The globe was lit up in rainbow colors on June 26, 2015 to celebrate the supreme court ruling which legalized same sex marriage.

[10] Celebrity chef Wolfgang Puck opened the fine dining revolving restaurant Five Sixty on the tower's rotating top level on February 11, 2009.

The middle floor of the tower is used for special events managed by Wolfgang Puck Catering, which is based at nearby Union Station.

The interior facility includes an interactive digital experience featuring information about Dallas landmarks, Reunion Tower itself, the events of November 22, 1963, live view high-definition cameras and more.
