Revetted Bunker
A revetted bunker is a sand hazard whose steep face is built from thin layers of turf stacked on top of one another, like bricks in a wall. It is most common on the links courses of Britain and Ireland and is a defining sight at The Open Championship.
What is a revetted bunker?
The word revetted comes from revetment, a term borrowed from engineering for a facing of stone, brick, or other material used to hold up an embankment. It traces back to the French revêtir, meaning to clothe or cover (Golf Course Industry). On a golf course, the material doing the covering is turf. A greenkeeper cuts thin slabs of grass with the soil and roots still attached, then stacks them layer by layer to form the wall of the bunker.
The result looks almost man-made, because it is. A revetted face rises steeply, sometimes close to vertical, in a series of visible grass steps. That stacked wall is what sets a revetted bunker apart from an ordinary sand trap, where the edge is usually a shallow slope blending into the surrounding ground.
Revetted bunkers belong to links golf, the seaside style played on sandy coastal land. They dominate the courses on The Open rota, from St Andrews to Royal Birkdale, and anyone watching the tournament will see players spend far more effort escaping them than attacking the green. Understanding the term comes down to picturing that stacked turf wall and knowing it was put there on purpose.
How a revetted bunker is built
Building a revetted face is slow, skilled work. A greenkeeper cuts turf into uniform strips, lays them grass-side down, and stacks them so each layer sits slightly back from the one beneath, giving the finished face a gentle backward lean rather than a perfectly upright wall (Tennis World USA). A single bunker can hold anywhere from 25 to 50 layers, depending on how deep and wide the trap is (Golf Monthly).
The scale of the job surprises most golfers. At Royal St George’s, an Open venue, only a handful of the 104 bunkers are natural. The rest are revetted, and the turf is grown on the club’s own nurseries a full year in advance, then cut into 12-inch strips and stacked like building blocks (BIGGA). A crew might spend two or three days on a single bunker.
Not all revetting uses living grass. Traditional turf faces wear down and have to be rebuilt every four to eight years, sooner on edges exposed to sun and wind (Pitchcare; Glenelg Golf Club). To cut that maintenance, many clubs now revet with synthetic turf, which can hold its shape for 20 years or more while keeping much of the classic look (GreenKeeping Magazine). A typical natural revetted bunker costs around £1,000 to build, though that figure moves with size and materials (Golf Monthly).
| Feature | Natural turf revetting | Synthetic turf revetting |
|---|---|---|
| Lifespan before rebuild | About 4 to 8 years | 20 years or more |
| Appearance | Classic look, weathers naturally | Very close match, differs only on close inspection |
| Maintenance | High: watering plus frequent rebuilds | Low |
| Best suited to | Traditional links and Open venues | Clubs wanting the look with less upkeep |
Revetted bunker vs pot bunker
Commentators use “revetted bunker” and “pot bunker” almost interchangeably, but the two words describe different things. Revetted refers to how the face is built, using stacked turf. Pot refers to the shape, meaning a small, deep, roughly circular bunker with steep sides (Tennis World USA).
The two often overlap. The most famous pot bunkers, such as the Road bunker beside the 17th green at St Andrews, are revetted, and their stacked walls are exactly what makes them so hard to escape. A bunker can be one without the other, though. Hell bunker on the Old Course is revetted yet enormous, nothing like a small pot (Top 100 Golf Courses). Old photographs of Bobby Jones at St Andrews even show the Road bunker with a natural, unstacked face, before it was revetted years later (Top 100 Golf Courses).
| Term | What it describes | Typical face | Where you see it |
|---|---|---|---|
| Revetted bunker | How the face is built (stacked turf) | Steep, layered wall | Links courses, Open venues |
| Pot bunker | The bunker’s shape (small, deep, round) | Steep, often revetted | Links courses |
| Standard bunker | A general sand hazard | Shallow grass or sand slope | Parkland courses worldwide |
A pot bunker is usually revetted, but plenty of revetted bunkers are far bigger than any pot.
Why links courses use revetted bunkers
Revetting began as a practical fix, not a design flourish. Scottish greenkeepers started stacking turf on bunker faces around the middle of the 19th century to stop coastal wind from eroding the sand and collapsing the edges (Tennis World USA; Golf Course Industry). On exposed links land with sandy soil and a constant sea breeze, a plain sand face simply blows away, while a stacked turf wall holds everything in place.
The strategic value came later and changed how the hazard was used. A steep revetted wall punishes a wayward shot far more than a shallow trap does. At the Old Course, architect Tim Liddy has noted that close to 90 percent of bunker shots are now played sideways or backwards, because the face leaves no other option (Golf Course Industry). Greenkeepers add to the difficulty by shaving the grass around the rim so more balls feed into the sand (Golf Monthly). From the mid-1970s onward, most bunkers on Open courses were revetted if they were not already, and architects Martin Ebert and Tom Mackenzie described what followed as an arms race to see how hard bunkers could be made (Top 100 Golf Courses).
There is a visual pull too. The layered face throws sharp shadows and gives a course the instantly recognisable look of traditional links golf. That appeal has carried the style well beyond Britain. When Pete Dye renovated Brickyard Crossing at the Indianapolis Motor Speedway in 1993, he built six deep, sod-stacked revetted bunkers, and American architects such as Lester George have since added them to inland courses far from any coast (Golf Course Industry).

Frequently Asked Questions
Why is it called a revetted bunker?
The name comes from revetment, an engineering term for a facing that holds up an embankment, which itself comes from the French revêtir, to cover. In a bunker, the covering is stacked turf.
Are revetted bunkers harder to play from than normal bunkers?
Usually, yes. The tall, steep face often blocks any direct route to the green, forcing a player to wedge out sideways or backwards and accept a dropped shot.
How long does a revetted bunker last?
A natural turf face typically needs rebuilding every four to eight years. Synthetic turf versions can last 20 years or more.
Are revetted bunkers only found on links courses?
They are most common on links courses in Britain and Ireland, but the style now appears on inland and parkland courses around the world, including several in the United States.
Is a revetted bunker the same as a pot bunker?
No, the two are different. Revetted refers to the build, pot to the shape. A pot bunker is usually revetted, but many revetted bunkers are far bigger than a pot.
