The investiture of Prince Charles – first in line to the British throne – as Prince of Wales took place at Caernarfon Castle on the 3rd of July, 1969.
Despite the general popularity of the event, some Welsh people felt the investiture was a sign of the subjugation of Wales. A large protest was held several weeks before, on the 6th of March.
