It is the largest of several small villages and dispersed settlements that make up Mechell Community Council area.
This describes how St Mechell was offered a gift of land in gratitude for a miraculous healing, to be demarcated by the route of a released hare.
The hare, under divine guidance, marked the full extent of what is now the parish of Llanfechell, where he then founded the monastery.
From 1734 to 1760 he kept a daily diary recording Anglesey life, social customs, personal and family dealings, farming practices and the weather.
His daughter married Fortunatus Wright, a brewer from Liverpool whose colourful life included periods as a privateer.
During the 18th century and following, in addition to its weekly market day the village held a fair several times a year, for the sale of livestock and produce.
[8] 'Menter Mechell' is an umbrella community venture, which helps facilitate a variety of activities and interest groups in the village.
[10] In addition to the three churches, there are six other listed buildings within the village (all grade II): There are four scheduled monuments close to the village: The standing stone 440 yards north of Llanfechell Church, known as Baron Hill Maen Hir, is a prehistoric standing stone (one of many such on Anglesey).
When removed from its socket, some 20 packing stones were found around its base, one of which had two 'pecked' engravings, a cupmark and a cup and ring mark.
Such rock engravings are very rare in North Wales, and its use as part of the construction of the standing stone implies a particular, if unknown, significance.
