Three standing castles can seen in Guernsey today.
It is believed that the construction of Castle Cornet began in 1206 shortly after King John lost Normandy - but not the Channel Islands - to the French Crown. Since this time, Guernsey has been of strategic importance during centuries of European conflict and Castle Cornet has stood guard over St Peter Port, defending the island against the threat of invasion.
Throughout its history, the castle has developed and expanded as military needs have evolved resulting in a fascinating but complex mix of medieval, Tudor, 18th century and German elements that combine to make up the castle as it stands today. No longer serving a military role Castle Cornet is one of Guernsey's premier tourist attractions.

Archaeological evidence has shown that a defence earthwork stood on this site in the early Iron Age. It is thought however that the earliest parts of the stone built castle that we see today date to the 15th century. In the 18th century several barrack blocks were built within the castle walls but were later demolished. During the Second World War the German occupying forces fortified the castle and the surrounding area, remains of which can be seen today. View site information sign...
