Llandwyn Island off the south west coast of Anglesey is the classic location within the British Isles for studying pillow lavas.

Pillow lava is lava which has erupted under the sea, as the lava spills out of vents its surface is rapidly cooled. The lava takes on the characteristic of toothpaste being squeezed form a tube and take on these notable Ã¢Â.Â.pillowÃ¢Â.Â. shapes.
