Every city and village with a population of less than 500,000 in the manner provided in this Division 66, may establish and maintain a municipal coliseum to be used for general educational and amusement purposes for the benefit of its inhabitants. For this purpose, the corporate authorities may levy a tax not to exceed .25% of the value, as equalized or assessed by the Department of Revenue, on all the taxable property of the municipality, for the establishment of such a coliseum, and thereafter may annually levy a tax not to exceed .05% of the value, as equalized or assessed by the Department of Revenue, on all the taxable property of the municipality, for the maintenance thereof. Those taxes shall be levied and collected in like manner as other taxes of the municipality are levied and collected for municipal purposes. This tax when collected shall be paid to the municipal treasurer and shall be designated as the municipal coliseum fund. This tax shall be in addition to all other taxes which the municipality is now or may be hereafter authorized to levy and collect, and shall be in addition to the amount authorized to be levied for general purposes as provided by Section 8-3-1.
     The foregoing limitations upon tax rates may be increased or decreased according to the referendum provisions of the General Revenue Law of Illinois.
