Coastal Fortifications

Jersey’s strategic position in the English Channel has left a legacy of defensive architecture spanning eight centuries. This collection features medieval strongholds like Grosnez Castle, 16th-century tidal fortresses, and 19th-century granite Martello towers designed to repel French invasions. The list also highlights the island's more recent history with well-preserved German bunkers and observation towers from the 1940s Atlantic Wall, including specialized casemates and heavy artillery positions integrated into the rugged coastline.
