There is so much more to see here that I suggest you visit at 3pm in the afternoon when you can avail of a very knowledgeable guide to show you around (the chapel is open from 10.30am to 12 noon and 3pm to 5pm each day).
Initially I assumed this little fellow was St George with his dragon but I have been reliably informed and that he is St Michel et le dragon! You can also see him at Le Mont St Michel which is another great trip to make one day!
I was intrigued to note the commemoration to St Maudez with the tiny Irish harp in the little stained glass window on the left side of the alter. This Irish prince had visited Brittany in the 6th century and gives his name to both the island of Maudez (near Ile de Brehat) where he built a monastery and the commune of St. Maudez in Cotes d'Armor.
