This belongs in the Buildings & Architecture section of the forum, so I'm moving it.
Yes, that building was one of the hardest hit in the storm. It was nearly demolished. This was the old Bank One Tower, built in 1974. It was the city's tallest at the time.
Several of Fort Worth's talls were heavily damaged by the tornado. Several other smaller buildings were either completely destroyed, such as the Calvery Cathedral. This is the site of the new Pier 1 Imports Headquarters tower. The 9-story Mallick Tower and Cash America Building were also almost destroyed. They were repaired however. One highrise was demolished due to the tornado damage and years of decay as it had been vacant for 15 years. The Landmark Tower at 380 feet tall with 30 floors was demolished. Not only was it Fort Worth's tallest building when built in 1957, but it is also the tallest building to ever be demolished in Texas.
