Monuments to visit Saint-Ouen

On the top of the cliffs, this castle was probably built in the 14th century. Only a few ruins remain: an ogival door, remains of ramparts and machicolations. The view is superb and you will have the possibility of sumptuous walks. The name of Grosnez would be of Viking origin. In old Norwegian nes is roughly equivalent to "promontory". The Vikings gave a name to each of the promontories they had to pass: Gris Nez, Blanc Nez, Nez de Jobourg. Gros would come from grjot which would mean "rock".

Starting from Grosnez Castel, a little further south and lost in the Jersey moors, is a needle-shaped rock over 60 meters high called the Pinnacle. It was a place of worship for thousands of years and is believed to date back to 4800 BC. From the point, you can clearly see Sark and Guernsey. A superb view on a sunny day and a great reward after a long walk in a rugged and sea-swept area. The fauna and flora here are superb. Get your walking shoes on!

Les Monts Grantez is a gallery dolmen in the commune of Saint-Ouen. This megalithic monument has been dated to the Middle Neolithic (between 4000 and 3250 BC). If it has lost its main table, it is still relatively imposing. This dolmen was discovered in 1839 and the excavations date back to 1912. Eight skeletons, animal remains and a beautiful variety of pottery were also found. It is a site with a rather intriguing atmosphere. A beautiful mystical walk in perspective, especially if the fog is of the part.
