of the church is its font, which dates from the late 12th century, or possibly even the first part of the 11th century. It measures by (external measurements) and is deep. It is rectangular and decorated on three sides. One of the shorter sides has a cross with four arms of equal length imposed on a ring; at the base are two small hemispheres, and the design is framed with bands (some plain, some decorated with chevrons or a twisted rope pattern). It has been suggested that the hemispheres are bee skeps. One of the longer sides has a row of arches forming an arcade above a pattern of lozenges. The other shorter side has a chequerwork pattern. The archeologist David Petts has noted that it is one of a number of fonts on Anglesey that has an area with little or no carving, perhaps because it was never anticipated that the plain side of the font would be seen or because the font was carved after being put in its position in the church. Although similar in style to other Anglesey fonts, its rectangular shape is "unique", according to Petts, and the cross on one side "finds no parallels among fonts of this period." One writer, the historian Peter Lord, has suggested that it was initially used as an altar. Accepting the 11th-century dating, Lord stated that "as an altar of the pre-Norman period it is a unique survivor in Wales and, indeed, in Britain". Petts considers this "unlikely", suggesting that it may originally have been a reliquary. The Friends of Friendless Churches describes the font as the building's "chief glory". It has also been called "the best of Anglesey's remarkable Romanesque series." It has similarities of design and style with the fonts of two other churches on Anglesey (St Llwydian's Church, Heneglwys and St Iestyn's Church, Llaniestyn) and with one of the stone crosses at St Seiriol's Church, Penmon. Assessment The church is a Grade II* listed building – the second-highest (of three) grade of listing, designating "particularly important buildings of more than special interest". It was given this status on 5 April 1971, and has been listed because it is "a rural Medieval church retaining its simple character." It is described by Cadw (the Welsh Assembly Government body responsible for the built heritage of Wales) as a church "of typical Anglesey type", where the 19th-century restoration work
