Santander Tower, formerly known as Thanksgiving Tower, is a 50-story, 197 m (646 ft) skyscraper at 1601 Elm Street adjacent to Thanks-Giving Square in downtown Dallas, Texas. At its completion in 1982, it was the second tallest building in Dallas, surpassing Elm Place. One year later, with the completion of 1700 Pacific, it became the third tallest, and it is currently the 8th-tallest building in the city. The building is connected to the Dallas Pedestrian Network and the Bullington Truck Terminal. Santander Tower is owned and managed by Woods Capital, and it was designed by the architecture firm HKS Architects. Formerly known as the Thanks-Giving Tower, it was renamed in 2020 after Banco Santander.
