The Cape Colony received responsible government in 1872, and with it came a growing sense that that the Colony should have its own arms. The laying of the foundation stone of the new colonialparliament building in May 1875 was considered as a good opportunity for the display of the colony's badge and flag.
The foundation stone of the colonial parliament was laid on 12 May1875 - and, according to the Cape Argus newspaper, "among the conspicuous features of the spectacle was the new colonial flag, hoisted aloft above the corner stone, with the heraldic shielding, surroundings and mottoes blazoned on the Union Jack and the Royal Standard floating in the breeze from the loftiest flagstaff in the centre".
