Listed building or place reference: OU0020 Historic site reference Property Grosnez Castle Road name La Route de Grosnez Parish St. Ouen LocationView on map Grade Listed Building Grade 1 Category Castles and forts Statement of significance A 14th century fortification site of exceptional significance to the history of Jersey. Context n/a External Description A ruined fortified circular stone enclosure with a gatehouse, curtain walls and rock cut ditch, with traces of simple buildings to the interior. The granite curtain wall is about 250 metres long and encloses an area roughly circular in shape. The walls are thickest on the landward (S) side - the other sides (N, E & W) being protected by natural steep cliffs some 60 metres high. The most substantial standing structure is the gatehouse, which was protected by a drawbridge and portcullis. There is a portcullis groove descending to passage level, and below the groove is a pit for a counterpoise type drawbridge. Flanking the gatehouse are two D-shaped towers (now reduced to about 2m high). The west tower has remains of two arrow slits at ground level. Between the gatehouse and the east tower is a ramp up to the former wall-walk. There are two other towers further around on the east and west sides, but beyond them the natural defences presumably made flanking towers uneccesary. In front of the gatehouse is a broad ditch cut through the solid rock, originally crossed by the drawbridge. Archaeological excavations of the ditch revealed 12 carved corbels from the gatehouse (now on display at La Hougue Bie Museum). Inside the walls can be traced the foundations of groups of modest structures.
