 The church is still used for worship by the Church in Wales , one of five in a group of parishes in the south of Anglesey . It is a Grade II listed building , a national designation given to " buildings of special interest , which warrant every effort being made to preserve them " , in particular because it is regarded as " a distinctive example of pre @-@ archaeological gothic revival work . " The 19th @-@ century clergyman and antiquarian Harry Longueville Jones said that it had been built in a " debased barbarous style , showing neither architectural science nor taste " .
