Sean,
Royal Guernsey (aka L'Ancresse) is my childhood club. Donald Steel has a write-up of Royal Jersey, La Moye and RG in his book Classic Golf Links.
Mackenzie Ross is listed as the primary architect at RG. It is a true links built on common land. Therefore anyone has the right of way over the holes including farmers who are allowed to graze their cattle in the rough !
Other hazards to be dealt with include a couple of neolithic stone monuments dating from thousands of years BC, Martello Towers and German Nazi bunkers from WWII.
This ancient set of rocks is dead in the middle of the 13th fairway, if you find the monument, you have to play it as it lies ! - the tee is on the top of the hill behind:
You feel you can be in danger of hitting this Martello Tower with a big slice on the 15th/16th holes:
The short downhill par 3 18th with Nazi concrete bunker just off from the line of play (a great view to finish a round):
