 St Nidan 's Church , Llanidan is a 19th @-@ century parish church near the village of Brynsiencyn , in Anglesey , north Wales . Built between 1839 and 1843 , it replaced the Old Church of St Nidan , Llanidan , which needed significant repair , providing a place of Anglican worship nearer to the village than the old church . Some items were moved here from the old church , including the 13th @-@ century font , two bells from the 14th and 15th century , and a reliquary thought to hold the remains of St Nidan . The tower at the west end has been described as " top heavy " and looking like " a water tower " .
