By the 1960s , sections of downtown had entered a period of decline . To commemorate the centennial of Wichita 's founding , the city razed The Forum and in its place built the Century II Performing Arts & Convention Center which opened in 1969 . The city government relocated to a new City Hall in 1975 . In 1981 , the former City Building reopened as the Wichita-Sedgwick County Historical Museum . In 1987 , construction finished downtown on the Epic Center office tower , the tallest building in the city and in the state of Kansas
