Ah, the 4th at Lawsonia -- the course's hardest par 3 (although Ron Forse may disagree). I've always thought of the 4th as "Redan-esque," as opposed to being a true Redan.
Excerpts from Bahto's GCA interview on templates:
"What more accurate way to describe a 'Redan' than Macdonald's own words? 'Take a narrow tableland, tilt it a little from right to left, dig a deep bunker on the front side, approach it diagonally, and you have a Redan.' Bear in mind when Macdonald says 'tilt,' he means it. At National, hole #4 falls over five feet from front to rear. Redans are usually around 190 yards (a formidable distance in the early days of golf) with numerous strategic options depending on wind direction and course conditions: Fly it to the green if you are able, lay-up and chip on hoping to make three, hit a running shot at the banked area fronting the green or even play left of the Redan bunker hoping for a better approach angle (not recommended!). Behind the green are usually deep sand pits to catch aggressive play."
I'd argue Lawsonia's 4th captures most of those elements. It provides options for how to play it. It has a deep bunker fronting left. Bunkers in back catch the overly aggressive play.
What it lacks is the high tilt to the right side of the green. Still, the green complex is accepting of a running draw, the kind of shot option that Redans, from my reading, are designed to accept, or not openly discourage.
I'm curious about two features that have creeped into discussions about Redans -- that of the "banked area" right of the green that can serve as something of an aiming point for a tee shot, with the result of boosting the shot toward the sloped green and a left-side pin position. Is the banked slope an essential element of a Redan? Is it a Redan if the hole has all of the other elements save for the banked slope? (I'd note that the 7th at Shinnecock, often described as the hardest Redan in golf because of its severely tilted green, appears to have no such banked slope.)
Secondly, does a downhill tee shot make a Redan (complete with the requisite characteristics) essentially not a Redan? Most Redans I've seen pictures of depict either an uphill tee shot or one in which the green is perched above the surrounding land, in part to provide the depth of bunkering left front essential to any Redan.
The GCA course reviews are full of descriptions and pictures of Redans -- Shinnecock, the National, Carmargo, Piping Rock, Fishers Island, Westhampton, Lookout Mtn., St. Louis, CC of Charleston, Yale, Yeamans Hall. Interestingly, Langford/Moreau built what appears to be a Redan at Culver Academies, with the required green tilt and bank lacking at the 4th at Lawsonia. The instigator of this thread has played Culver Academies; thoughts on the similarities and contrasts of the two? (To my eyes, the 15th at Carmargo most closely approximates the look of Lawsonia's 4th.)
In GCA discussions about template holes, I'm struck by the melding of debate about how the hole should play, compared to how the hole should look. One can't help but think Langford and Moreau had seen plenty of Redans when designing the 4th at Lawsonia; it certainly looks the part. That it doesn't play exactly as a Redan suggests Langford was more interested in designing his own version of the Redan template, as opposed to truly replicating it. But that's not too far from what Macdonald and Raynor did; Macdonald at the National didn't seem to be interested in designing and building exact duplicates so much as utilizing design concepts to mirror the strategies of the great holes he saw overseas.
