Santander Tower, Skyscraper in downtown Dallas, US

Santander Tower is a 50-story, 197 m modernist office skyscraper at 1601 Elm Street in downtown Dallas, next to Thanks-Giving Square. HKS Architects gave it recessed corners that reduce its apparent bulk and allow up to 16 corner offices per floor. Its floors cover about 130,064 m², and 12 of the 50 floors are being converted into 228 residential units.

Santander Tower was completed in 1982 as Thanksgiving Tower, named after the adjacent Thanks-Giving Square, and was designed by HKS Architects in a modernist style. It opened as the second-tallest building in Dallas, surpassing Elm Place, then fell to third in 1983 when 1700 Pacific was finished; it now ranks eighth in the city. Woods Capital bought it out of foreclosure in 2013 and renamed it in 2020 after Banco Santander.

The tower takes its name from Thanks-Giving Square, the adjacent plaza it borders on Elm Street. It links into the Dallas Pedestrian Network and the Bullington Truck Terminal, so pedestrians reach it without crossing downtown traffic. The building was renamed Santander Tower in 2020 after Banco Santander.

Santander Tower occupies the block at 1601 Elm Street beside Thanks-Giving Square. Its lower levels connect to the Dallas Pedestrian Network and the Bullington Truck Terminal, letting visitors walk to nearby downtown addresses through covered routes. The tower is owned and managed by Woods Capital.

In 2013 Woods Capital bought the tower out of foreclosure and spent about $45 million on a repositioning campaign. Lobbies, the plaza, mechanical systems and common areas were upgraded, and occupancy rose as a result.
