Saint Cybi was said to be the cousin of Saint David (~500- 1st March 589AD, there is uncertainty to the dates), the Patron Saint of Wales, and the friend of Saint Seiriol who founded his cell at Penmon on Ynys Môn (Anglesey) with whom he would regularly meet.
Specific Location: Holyhead
Caer-y-Twr is the remains of an Iron Age hill fort on the summit of Holyhead mountain (Mynydd Twr) 220 metres in height. Due to its position, it did not need much additional defence, but it had a stone rampart on the northern and eastern sides enclosing an area of roughly seven hectares. The site of the hill fort now contains mostly rubble, but the walls can still be identified.
In 1743 a farmer near Holyhead, Anglesey is alleged to have witnessed a ‘boat’ sailing in the clouds at about 1500 feet. The story appeared in the ‘Flying Saucer Review’ in 1971.
