Nevermind Big Nellie at Portrush, anything at Sand Hills, or the 4th at Sandwich. The greatest bunker is at St Enodoc's 6th, taller than any of those and taller than the bunker at the 13th at Pacific Dunes. I had a pic, but I can't find it.
There also used to be an enormous bunker to the right of the 15th green at Cruden Bay. I'll copy it sometime and post (it has about 20 wooden steps going down into it!).

Darwin's book 1910?
Herbert Fowler did a major redesign and I believe this was after Darwin's book.
