Editing Holyhead (section)

==Etymology==
The town's English name, ''Holyhead'', has existed since at least the 14th century. As is the case with many coastal parts of Wales, the name in English is significantly different from its name in Welsh. It refers to the holiness of the locality and has taken the form ''Haliheved'', ''Holiheved'', ''Le Holyhede'' and ''Holy Head'' in the past. The Welsh name, ''Caergybi'', derives from the fortification around which the town developed. The locality was known by such names as ''Karkeby'' ('seat of Cybi'), ''Castro Kyby'' ('the fortified military camp of Cybi'), and ''Kaer Gybi'' (Cybi's resting place).<ref>{{cite book|url=https://books.google.com/books?id=9cxRDwAAQBAJ&pg=PA23|page=23|title=The Place-Names of Wales|first=Hywel Wyn |last=Owen|year=2015|publisher=University of Wales Press|isbn=978-1783161652}}</ref>

Prior to the influence of the fort on the name, the hamlets which came before it were likely known as ''Llan y Gwyddel'' ('church/parish of the Irish') and ''Eglwys y Beddi'' ('church of the graves').<ref>{{cite book |last1= Jones |first1= Gwilym|last2= Roberts |first2= Tomos |date= 1996|title= Enwau Lleoedd Môn : The Place-Names of Anglesey|location= Bangor, Wales |publisher= University of Wales Press |pages= 122–123|isbn= 0-904567-71-0}}</ref>
