This was the end of the monarchy.

Louis, the brave queen and her children, and Princess Elizabeth, sister of the king, were removed from the Assembly to the prison in "The Temple," and the National Convention formally declared France a republic.
The grim prison to which they were taken, with its central square tower flanked by four round towers, had stood since the time of Philip Augustus.
