Mechell is a community in the north of the Isle of Anglesey, Wales. Llanfechell is the largest village within the community area. Tregele, Mynydd Mechell, Bodewryd, Rhosbeirio and Carreglefn have a more dispersed settlement pattern. The antiquity of these settlements is shown by the presence of 6 medieval (or older) churches and some 16 more ancient sites dating back into prehistory.
The population of the community in 2011 was 1,293.
Mechell's settlements are all on inland situations, although a narrow strip of land reaches up as far as the north coast of the island, east of Cemaes Bay, in Llanbadrig Community. To the east is Cylch-y-Garn Community, and to the south is Tref Alaw and Rhosybol.
There are three wards within the Mechell community area, with a total of 10 councillors representing Llanfechell, Mynydd Mechell and Carreglefn, plus a chairperson.
The oldest of the settlements appears to be Llanfechell, named, as is the larger community, after the 6th century saint Mechell, reputedly a Breton missionary. Tradition has it that he is buried in Llanfechell. The large number of prehistoric sites attest to human habitation across the Community since well before that.
There is a very detailed account of daily life in the Mechell area during the 18th century, within the diaries of William Bulkeley, (1691-1760). He lived at Brynddu, a house on the edge of Llanfechell, and kept a daily record of Anglesey life from 1734 to 1760.
The land of Mechell Community is a settled agricultural landscape, with a network of small farms. The longstanding importance of arable agriculture is shown by the remains of two watermills and four windmills in the Mechell area: Meddanen Water Mill and Melin Mechell Windmill (also known as Minffordd Mill and Melin Maen Arthur), SH362902 are close together so could have been worked by the same miller, utilising water and wind as available.
