The first development on the CENTURY SQUARE site was the Gateway West tower, known in later years as 1801 Avenue of the Stars. The building was completed in 1963, the year before business began at the adjacent shopping center. This historic Mid-Century Modern (and Welton Becket-designed) structure was knocked down in April 2015, in the name of "progress". It has been replaced with an enlargement of the mall.
