Hangman Island is an uninhabited rocky tidal island located 150 metres to the north east of Kitchen Porth on the east coast of Bryher. The island's name may comes from a time in the past when mutinous sailors were hanged on it, possibly by Admiral Blake during the English Civil War. Alternatively, the name may be derived from the Cornish an-men, meaning the rock. The current gibbet on top of the island is modern.
Hangman Island can be accessed on foot at low tide from Bryher. You have to cross a sandy beach and then about 50 metres of seaweed covered boulders, followed by a short scramble up the rocks onto the island. The island is covered in grass, bracken, Escallonia rubra, scurvy grass and agapanthus. The exposed rocks are covered in grey-green, black and gold lichens.
