Ile Agois is Jersey's smallest offshore islet, and the closest to the shore. It is only 500 yards square and separated by a gorge only a few feet wide through the 250 foot high cliffs. Because it is inaccessible today it is covered in wildflowers, including primroses, bluebells and the royal fern.
There are signs of previous occupation, the outline of 14 ancient hut circles having been traced. Neolithic pottery and flint arrowheads have been found, indicating probably occupancy in the 9th century BC, or earlier, and seven coins of Charles the Bald, grandson of Charlemagne, indicate further occupancy in the 9th Century AD. It is possible that at this time the islet had not been cut off from the cliffs and was used as a place of refuge.
