One of Guernsey’s most impressive attractions is a 13th-century fortification on the edge of the capital that today hosts numerous museums and formal gardens.

The outline of Castle Cornet dominates views of the ocean from the vantage point of St. Peter Port. This medieval monument is one of the main attractions in Guernsey’s charming capital, both for its extensive fortifications and the numerous museums it contains. Stroll around the ramparts of the castle, then head inside to see exhibits on maritime and military history, as well as several elegant gardens. 

Some say the island outside St. Peter Port has been inhabited since the Neolithic and Roman eras. Look for parts of the castle dating to the middle of the 13th century. These earliest remnants of the original castle still stand, although the structure was subsequently redeveloped throughout the ensuing centuries.

Wander around the fortifications and follow interpretive trails throughout the castle. Young children can pick up activity sheets while exploring. Make sure you’re in the castle at noon, when a Napoleonic cannon is fired in a traditional ceremony with costumed “keepers” following military drills. 

The outside of the castle also features four pleasant formal gardens, once the private spaces of the officers and politicians who lived here. Stop by the Governor’s Garden to admire the topiaries here.  

Visit one or all of the five museums that are housed within the castle. Charting the 800 years of the castle’s existence, the Story of Castle Cornet is the place to go to learn about the fortress itself. See a mysterious skeleton that was found with a doubloon in its stomach. 

Picture yourself as a seafarer in the Maritime Museum, which also features a display of maritime-themed artworks. The other three museums are dedicated to the history of Guernsey’s air and army regiments. 

Walk to Castle Cornet from the bus terminus in St. Peter Port in just 10 minutes. Children and students can ask for reduced ticket prices or you can pick up a Discovery Pass for access to the castle and other sites, including the Guernsey Museum. The castle is open throughout the year.
