The City Center Building, known briefly as Centennial Tower, is clearly visible as the tallest building in Hayward, California. It is the tallest in Hayward, and was previously the second tallest, until the 2013 razing of Warren Hall on the Cal State East Bay campus. It is currently an abandoned building located between Foothill Boulevard and City Center Drive, in the City Center section of Downtown Hayward, adjacent to the PlazaCenter mall.
