What is grosnez castle?

Grosnez Castle is a ruined castle located on the island of Jersey, in the English Channel. It was built in the 14th century by Sir John des Roches, a prominent military figure and advisor to Edward II. The castle was strategically placed on a headland overlooking the sea, and was used to protect the island from French invaders.

The castle was fortified with high walls and towers, and had a moat surrounding it. It also had a great hall, a chapel, and living quarters for the soldiers stationed there. The castle was partially destroyed by artillery fire during the English Civil War in the 17th century, and fell into disuse and decay.

Today, the ruins of the castle are a popular tourist attraction, and are managed by the Jersey Heritage Trust. Visitors can explore the site and learn about its history through information panels and guided tours. The castle is also a popular spot for hiking and scenic walks, as it offers stunning views of the coast and surrounding countryside.
