The Caernarfon Mithraeum is a Mithraic temple or Mithraeum. It was located 137 meters north-east of the Roman castram of Segontium on the outskirts of modern Caernarfon in Gwynedd, Wales. The remains were discovered by accident on 2 April 1958 and excavated by the National Museum of Wales in August of the following year under the direction of George Boon. The site was found to be already damaged by a sewer trench which cut across the anteroom and had removed part of the southeast corner, but the majority of the temple could be excavated. The excavators noted the site was quite marshy and this suggested that a stream had once flowed close to the temple at the bottom of the shallow valley. The marshy conditions caused the mechanical excavator to frequently fall into the excavation, causing further damage.

Caernarfon's town walls are a medieval defensive structure around the town of Caernarfon in North Wales. The walls were constructed between 1283 and 1292 after the foundation of Caernarfon by Edward I, alongside the adjacent castle. The walls are 734 m (2,408 ft) long and include eight towers and two medieval gatehouses. The project was completed using large numbers of labourers brought in from England; the cost of building the walls came to around £3,500, a large sum for the period. The walls were significantly damaged during the rebellion of Madog ap Llywelyn in 1294, and had to be repaired at considerable expense. Political changes in the 16th century reduced the need to maintain such defences around the town. Today the walls form part of the UNESCO world heritage site administered by Cadw. Archaeologists Oliver Creighton and Robert Higham describe the defences as "a remarkably intact walled circuit".

The Battle of Twthill took place at Caernarfon in North Wales on 2 November 1401 during the revolt of Owain Glyndŵr. Glyndŵr's success at the Battle of Mynydd Hyddgen the previous June had provided the revolt with fresh impetus, and the battle may be seen as indicative of his determination to foster revolt in the north-west after months of relative inaction in that area. In symbolic terms, the battle is most famous as the first occasion on which Glyndŵr flew his flag bearing a golden dragon on a white field, recalling the symbolism of Uther Pendragon, and thereby more solidly drawing comparisons between his revolt and Welsh political mythology of the time, which drew heavily on the image of the mab darogan or chosen son, who would free Wales from subjugation. Little is known about the particulars of the fighting; the battle ended inconclusively, with 300 Welsh soldiers reported dead, but the isolation of Caernarfon and Glyndŵr's ability to attack English positions in Wales with impunity was amply demonstrated.
