Republic Center, Modern skyscraper in Central Business District, Dallas, US

Republic Center is a mixed-use complex on a full city block bounded by Ervay, Bryan, St. Paul and Pacific streets in downtown Dallas. Its 36-story tower, completed in 1954, has a facade of interlocking aluminum plates bearing the bank's four-pointed star and a 150-foot spire called the "rocket". A 50-story companion tower, finished in 1964, stands beside it.

The building was completed in 1954 and initially held the title of tallest structure west of the Mississippi River. Its construction marked Dallas's emergence as a major financial hub and prompted subsequent development throughout the downtown area.

The complex's aluminum cladding carries Republic National Bank's four-pointed star, repeated across the facade. At the Ervay Street entrance, bronze letters set Karl Hoblitzelle's 1945–1965 dedication to faithful public service. The former banking lobbies now hold offices and shops.

The building sits near DART rail stations and connects to the downtown tunnel system for pedestrian movement between adjacent blocks. Ground-level retail spaces offer orientation points when navigating the surrounding streets.

The spire on Gables Republic Tower is an abstracted version of Republic National Bank's four-pointed star, nicknamed the "rocket". Its rotating beacon was switched off once taller buildings surrounded it, and the spire is now lit from below at night. The bank's four-pointed star is also worked into the interlocking aluminum plates cladding the towers.
