Anything to the contrary hereinbefore notwithstanding, and for the benefit not of property but of persons attendant therein, no license shall be issued for the sale of alcoholic beverages within two hundred feet of any church or public schoolhouse or private schoolhouse not conducted for pecuniary profit, except to manufacturers, wholesalers, hotels, clubs and fraternal organizations which owned or were actually in possession of the licensed premises on December sixth, one thousand nine hundred and thirty-three. The protection of this section may be waived at the issuance of the license and at each renewal thereafter, by the duly authorized governing body on authority of such church or school, such waiver to be effective until the date of the next renewal of the license. Said two hundred feet shall be measured in the normal way that a pedestrian would properly walk from the nearest entrance of said church or school to the nearest entrance of the premises sought to be licensed.

The prohibition contained in this section shall not apply to the renewal of any license where no such church or schoolhouse was located within two hundred feet of the licensed premises as aforesaid at the time of the issuance of the license, nor to the issuance or renewal, or both, of any license where such premises have been heretofore licensed for the sale of alcoholic beverages or intoxicating liquors, and such church or schoolhouse was constructed or established, or both, during the time said premises were operated under said previous license.
