Reunion Tower is a 561 ft (171 m) observation tower and one of the most recognizable landmarks in Dallas, Texas. Located at 300 Reunion Blvd. in the Reunion district of downtown Dallas, the tower is part of the Hyatt Regency Hotel complex, and is the 15th tallest building in Dallas. A free-standing structure until the construction of an addition to the Hyatt Regency Dallas in 2000, the tower was designed by the architectural firm Welton Becket & Associates.
Reunion Tower was completed in 1978 as part of an urban redevelopment project that also renovated the historic Union Station, that today services Amtrak, Dallas Area Rapid Transit, and the Trinity Railway Express to Dallas-Fort Worth International Airport and Fort Worth. Reunion Tower reopened on February 9, 2009, after closing for major renovations on November 16, 2007.
