Cann Office – An inn and post house which formerly bore the symbol othe f a can or cans on its sign (Enid Pierce Roberts in National Library of Wales Journal 18). Can here evidently means 'a vessel for holding liquids, a drinking vessel'. The name has caused some confusion and misguided attempts have been made to interpret it as containing military cannons, ecclesiastical canons and caen, 'layer, coating', with cfos, 'ditch'.
