Grosnez Castle

Grosnez Castle is a ruined 14th-century castle in St Ouen, situated in Grosnez in the north-west corner of the island of Jersey in the Channel Islands. 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.

The name Grosnez comes from the old Norse words for ‘grey headland’ – grar nes which is an accurate description of the site when seen from the sea.PC Elizabeth Longbottom

It was built by Sir John des Roches around 1330, with its purpose being to provide the local farmers with a place of safey from French attacks. The French captured however the castle in 1373 and 1381 and was probably demolished around the time of the French occupation of Jersey (1461–1468). Archaeologists who have studied the ruins suggest that the castle was deliberately destroyed, rather than left to crumble over time.Photo Credit James Bedding

The castle’s position on a clifftop some 60 metres above the sea means that the natural features of the site protect it on three sides. A ditch dug into the rock provides protection on the fourth side. The remains of ruined walls, mostly footings, are still present. A drawbridge and portcullis protected the gatehouse, which is the only substantial surviving remnant, and would have made it difficult to capture. Photo Credit Jill Browne
