Agorodd y Sea Shanty ei ddrysau ym mis Gorffennaf 2016 ar ôl i’r sylfaenydd, Philip Brown, a Chyngor Sir Ynys Môn gydweithio ac ar ôl iddo gael cyllid oddi wrth Croeso Cymru. Saif yr adeilad newydd sbon hwn y tu ôl i brif draeth Trearddur a’r twyni tywod ac mae ganddo le i 160 y tu mewn a 55 y tu allan.
The Sea Shanty opened its doors in July 2016 following a coordinated effort from its creator Philip Brown, Anglesey County Council and funding from Visit Wales. Located  behind the main beach of Trearddur Bay, this brand new build sits behind the sand dunes and has 160 covers inside with a further 55 outside.
