Caernarfon, United Kingdom

In 1911, David Lloyd George, then Member of Parliament (MP) for Caernarfon boroughs, which included various towns from Llŷn to Conwy, agreed to the British royal family's idea of holding the investiture of the Prince of Wales at Caernarfon Castle. The ceremony took place on 13 July, with the royal family visiting Wales, and the future Edward VIII was duly invested.

In 1955, Caernarfon was in the running for the title of Capital of Wales on historical grounds but the town's campaign was heavily defeated in a ballot of Welsh local authorities, with 11 votes compared to Cardiff's 136. Cardiff therefore became the Welsh capital.

On 1 July 1969, the investiture ceremony for Charles, Prince of Wales was again held at Caernarfon Castle. The ceremony went ahead without incident despite terrorist threats and protests, which culminated in the death of two members of Mudiad Amddiffyn Cymru (Welsh Defence Movement), Alwyn Jones and George Taylor, who were killed when their bomb – intended for the railway line at Abergele in order to stop the British Royal Train – exploded prematurely. The bombing campaign (one in Abergele, two in Caernarfon and finally one on Llandudno Pier) was organised by the movement's leader, John Jenkins. He was later arrested after a tip-off and was sentenced to ten years imprisonment.

In July 2019, Caernarfon hosted a rally for Welsh independence. The event, organised by AUOB (All Under One Banner) Cymru, included a march through the town centre. Organisers estimated that roughly 8,000 people joined the march on the town square; local authorities confirmed at least 5,000 attendees. The event featured a number of speakers including Hardeep Singh Kohli, Evra Rose, Dafydd Iwan, Lleuwen Steffan, Siôn Jobbins, Beth Angell, Gwion Hallam, Meleri Davies and Elfed Wyn Jones. Talks covered criticism of Brexit and Westminster with advocating Welsh Independence.

The history of Caernarfon, as an example where the rise and fall of different civilizations can be seen from one hilltop, is discussed in John Michael Greer's book The Long Descent. He writes of Caernarfon: Spread out below us in an unexpected glory of sunlight was the whole recorded history of that little corner of the world. The ground beneath us still rippled with earthworks from the Celtic hill fort that guarded the Menai Strait more than two and a half millennia ago. The Roman fort that replaced it was now the dim brown mark of an old archaeological site on low hills off to the left. Edward I's great grey castle rose up in the middle foreground, and the high contrails of RAF jets on a training exercise out over the Irish Sea showed that the town's current overlords still maintained the old watch. Houses and shops from more than half a dozen centuries spread eastward as they rose through the waters of time, from the cramped medieval buildings of the old castle town straight ahead to the gaudy sign and sprawling parking lot of the supermarket back behind us.
