This church was built in 1844 by the diocesan architect, Henry Kennedy to replace the old church, the site of which lies to the east in the present churchyard. Built in the Lombardic Romanesque style, it has a nave, chancel, west bellcote, south porch and north vestry. It is constructed from roughly coursed rubblestone blocks with tooled ashlar dressings and has a continuous chamfered plinth and cill band. It also has steep-pitched slate roofs with coped verges and strong moulded cornices.

It is listed as an early church of Henry Kennedy, architect to the diocese of Bangor from the 1840s until his retirement in 1894. Llanllechid is one of his most distinctive buildings and shows him working in the neo-Norman style favoured during the earlier part of his career.
