Longer versions of the name are thought to have first been used in the 19th century in an attempt to develop the village as a commercial and tourist centre. The long form of the name is the longest place name in the United Kingdom and one of the longest in the world at 58 characters (51 "letters" since "ch" and "ll" are digraphs, and are treated as single letters in the Welsh language). The village is still signposted Llanfairpwllgwyngyll, marked on Ordnance Survey maps as Llanfair Pwllgwyngyll and the railway station is officially named Llanfairpwll, a form used by local residents. The name is also shortened to Llanfair PG, sufficient to distinguish it from other places in Wales called Llanfair (meaning "[St.] Mary's church").
