Peist is a huge, amphibious water monster described as a worm, dragon, [1] or serpent. [2] Peists inhabit the bottoms of venerated lakes in Ireland. [2]

Sightings of various peists have been recorded from early times to the mid-twentieth century. [1] The legendary Saint Patrick drove out all the serpents of Ireland, the Peists among them. [1]

The most recent sighting of a peist took place in 1954 in Lough Fadda in Ireland. [1]
