Grosnez Castle is a ruined 14th-century castle in St. Ouen, situated in Grosnez in the north-west corner of the island. Philippe de Carteret held it against the French when they held half of Jersey between 1461 and 1467, but it has been a ruin since the mid-16th century. Today, the ruins are open to the public. with concrete steps that lead from the rear of Grosnez Castle to an automated signal station where you will have fantastic views across to the other Channel Islands.
